Understanding Basic Mathematical Terms: Addition, Subtraction, Multiplication, and Division

Understanding Basic Mathematical Terms

Understanding mathematical terms is vital for everyone, from students to degreed professionals. Math is used on a daily basis in all aspects of life, and it is important to know the basic terminology before taking any math courses.

Common Factors – Two numbers that divide evenly into each other. Complementary Angles – Two angles that together equal 180 degrees.


Addition is an operation that finds the sum of two or more numbers. It is also called combining and it is one of the four basic operations in math. Addition is used in everyday life when people are counting items, calculating how many bees went out to suck nectar together or determining the total number of eggs found in an egg hunt.

A good practice when adding numbers is to break them down according to their place values so that it is easier for the mind to keep track of them as they are added together. Adding multiple digit numbers is easier when they are grouped together into groups of tens and ones, for example 7 + 5 = 12.

The addition symbol is represented by the plus sign (+). Addition is a binary operation and as such it is commutative. It is also associative, meaning that the order in which you add numbers does not affect the result.


Subtraction is an arithmetic operation that involves taking away one number from another. It’s a great way to get children thinking about the difference between two numbers, and is an important mathematical concept for them to understand.

Children can start learning subtraction in Year 1 using the resources that are available on Twinkl, such as these Subtraction from 20 number line worksheets. These can be a great starting point for subtraction, and also help children build confidence with inverse operations, such as addition through subtraction.

In the case of subtracting integers, subtraction follows certain predictable patterns. For example, the integers a and b are equal if (a + b) 0 or a – b = 0 or a – b > 0. Subtraction is also anticommutative, which means that the order in which you subtract numbers does matter. For instance, if you subtract 7 from 10, the answer is 10 – 7. This is a simple but essential property of subtraction.


Multiplication is the process of adding groups of numbers together to get a larger number. For example, if you have two groups of three ice creams, the total number is 6 ice creams. If you have a third group of three ice creams, the total is 12 ice creams. The first number, called the multiplicand, is added to the second number, called the multiplier, which then gets repeated until you have the final product. This is also known as the principle of repeated addition.

It is important for students to understand the concept of multiplication because it is one of the four basic arithmetic operations, along with addition, subtraction, and division. It is also the basis of algebra. Multiplication is commutative, which means that the order of the numbers doesn’t affect the result. For example, 2 groups of 3 x 4 groups of 3 gives the same answer as 5 groups of 3. It is easier for students to visualize this when they use multiplication tables, with rows and columns of numbers.


The division operation is the inverse of multiplication. It is used to share a whole number, the dividend, into equal groups, or parts, called the divisors. The remaining amount is the quotient. When division is done correctly, the quotient and remainder are the same.

Children will learn about division in primary school starting from Year 1 and it is usually the trickiest of the four basic operations for children to grasp. Dividing by fractions involves understanding what a quotient is and using divisibility rules.

The division symbol is / and it is written as either (Divisor x Quotient) or (Divisor + Quotient). Unlike addition and multiplication, which are both distributive, division is not, in general, commutative. This means that the order in which numbers are divided can change their result. This is known as the division algorithm. In particular, division by any nonzero element of a ring cannot always give a positive integer.

Math: The Basics

How to Define Basic Math

Whether you’re running your own business or just want to balance your bank account, having good math skills is essential. Math teaches you how to add, subtract, multiply and divide.

Most people think of “mathematics” as the subjects taught in high school curricula, such as geometry and algebra. However, math is much more than that.


Arithmetic is a part of math that deals with numbers and the operations performed on them. It includes addition, subtraction, multiplication, division and even the raising of numbers to powers in some cases. It is considered as the oldest method of calculating. Brahmagupta the Indian mathematician is known as the ‘father of arithmetic’ and Carl Friedrich Gauss proposed the fundamental theory of arithmetic in 1801.

There are four basic arithmetic operations: addition, subtraction, multiplication and division. These are the building blocks of the other math concepts like fractions, decimals, ratios and proportions. Besides these, math students also study percents, rounding and different word problems. The bridge between arithmetic and other more advanced concepts is algebra. These math formulas are very important as they help students learn and understand the different aspects of math better. These formulas include the following: sum can be related to addition, product can be related to multiplication and quotient can be related to division.


Along with arithmetic, geometry is one of the oldest branches of math. It deals with the study of shapes, sizes, parameters, measurements and angles of various figures.

A polygon is a group of straight lines or rays that meet at the same point and form a regular pattern. They can have 5, 6, 7, 8, or more sides and varying angles. The angles of a polygon can be acute, obtuse, or right. Geometry also includes the study of parallel lines, transversals and angle measures.

Kids learn the importance of formulas and theorems in geometry. They also learn the different types of shapes, their dimensions and properties like area, perimeter, volume, etc. They also learn about the various shapes like circle, square, cube, cylinder and sphere. Geometry also covers the concept of 2-dimensional shapes and 3-dimensional solids. Flat geometry involves the study of two-dimensional shapes having length and width, while solid geometry studies 3D shapes like cubes, prisms and spheres.


Algebra is the branch of Mathematics that uses letters to represent objects, numbers or expressions. It is an important part of basic math because it develops problem-solving skills, prepares students for higher-level arithmetic and is required in many college majors and jobs.

It also helps to understand the concepts behind formulas, which are standard-derived equations that form a foundation of almost all mathematical calculations. These equations provide finite ways of managing infinitely many values: The formula pr2 selects one value from an infinite number of possibilities for the area of a circle of radius r.

Modern algebra is a generalization of the concepts in elementary and arithmetic algebra to more abstract classes of algebras. This includes groups, rings and fields. It also includes the theory of vector spaces, well orderings and algebraic varieties.


If your child isn’t familiar with the fundamentals of math, he or she will struggle to learn new concepts. This is why it’s crucial to teach these skills early on.

Arithmetic is the basic branch of math that focuses on adding, subtracting, multiplying and dividing numbers. It includes the basics of number theory such as greatest common factor, least common multiple and prime factors.

Addition means putting together two numbers to make a larger one. Subtraction is the opposite, taking one number away from another. Multiplication is the process of combining numbers by repeating addition. Division is splitting a whole into equal parts or groups.

The next step after arithmetic is algebra, which uses symbols to represent numbers in equations. It also involves understanding functions, variables and expressions. A strong foundation in arithmetic and algebra is essential before attempting more advanced concepts like geometry.

Mastering the Four Basic Mathematical Operations

Learn the Four Basic Mathematical Operations for Codewars and Hackerrank

You’ll need to know the four basic mathematical operations – addition, subtraction, multiplication and division if you want to complete Codewars or Hackerrank problems. You can also use the expression() function to perform image math.

The function takes three arguments – operation(string/char), value1(number) and value2(number). It returns the result of those numbers after applying the chosen operation.


Addition is the basic mathematical operation of combining two or more values to produce their sum or total. It’s one of the four operations that comprise arithmetic, and is used to calculate things like the cost of groceries or the score in an exam.

Performing addition is one of the earliest tasks that young children learn, even before counting. It’s also an essential skill for learning the decimal system and using mechanical aids such as the abacus.

One of the most important properties of addition is that it’s commutative. For any three numbers a, b, and c, it doesn’t matter in which order they are added; the result will always be the same. This is true for any binary operation that adds elements, and extends to more general concepts such as disjoint union and wedge sum in category theory. The commutative property is also extended to the inverse of addition, subtraction. This is known as the commutative law of addition.


Subtraction is the process of taking one number away from another. It is one of the four primary arithmetic operations along with addition, multiplication, and division. Subtraction is also sometimes referred to as minus and less than.

Like addition, subtraction is a binary operation. As such, it can be performed in either order (a – b or b – a). In either case, the result will be the same. It is also important to note that subtraction is not commutative, meaning that changing the order of operations can yield different results.

For example, if we subtract 5 from 2, the resulting difference will be -3. As with addition, children should learn about subtraction using objects and games such as this Greedy Monster Subtraction Dice Game to develop confidence. They should then practice subtraction in a variety of contexts, including word problems and number lines. Eventually, they should be able to subtract any two numbers on the number line.


Multiplication is the process of adding a number to itself multiple times, resulting in an increased value. It is one of the four basic arithmetic operations along with addition, subtraction and division. Multiplication is a fundamental concept that allows individuals to solve complex calculations in many professional fields, including architecture and business.

The order of the numbers multiplied does not affect their product. For example, the number 5 times itself results in 15 because the number 1 is carried over to the digit space after the 5.

The mnemonic acronym PEMDAS explains the process of solving an expression with multiple elements that require a mixture of multiplication and division. The process is to address all of the multiplication and division elements in a given equation before proceeding with the addition and subtraction elements. This is a common strategy to help students learn the most important multiplication facts. Then, they can easily recall these when needed to solve a problem.


Division is an important mathematical operation that involves sharing a number into equal groups. This is one of the four basic operations that children learn in elementary school – along with addition, subtraction and multiplication. Despite its importance, many students find it the trickiest of the four to understand and master.

The division of two natural numbers gives an integer quotient and a remainder, for example 12 divided by 4 gives 3 in each group (with a remainder of 1 remaining). This type of division is also called integer division with remainder or Euclidean division.

Unlike addition and multiplication, division is not commutative, and the order in which a number is divided can change the result. Similarly, division by zero does not yield any result in most systems and entry of such an expression into calculators usually results in an error message. However, there are some algebraic structures that define division differently: for example, the division ring of a polynomial over a field contains all integers that divide evenly by that polynomial.
