Learn Class 5 Math - Computation Operations

During the early age, each student learns to know numbers. Moreover, these numbers play a great role in performing the arithmetic operations, which are essential to understand to shape the child’s future. So, without taking much time, let us understand Arithmetic operations.

Arithmetic operations accompany real numbers that help in performing Addition, Subtraction, Division and Multiplication.

The Four Arithmetic Operations

Addition

The addition is considered the most basic operation that comes under its Arithmetic. In this, the two quantities are combined into a single quantity to form a single sum.

e.g., you have a box of 3 chocolates and a box of 4 chocolates. If you mix all the chocolates in one box, you will have seven chocolates. To represent this into mathematical terms, it will be written as:

3 + 4 = 7

Subtraction

The Opposite of Addition is subtraction. In this, we do not add the two numbers. Instead, we subtract (remove) them.

e.g., suppose that you have eaten the 2 chocolates from the total number of chocolates that were 7. You will have 5 chocolates left.

7 − 2 = 5

Multiplication

The product of x and y is the result of x added y times concurrently. For example, one method of counting 7 chocolates of 2 boxes is to add the groups together:

E.g., you have to multiply 4 chocolates and 3 chocolates. To get a product, it will be calculated as:

4 X 3 = 12

Division

The division is the inverse of multiplication. Instead of multiplying numbers concurrently to get a higher value, you break a number into a smaller value, called the outcome. Again, to respond to the box example, splitting up a group of 6 boxes into 12 equal groups results in 2 groups of 6 boxes:

12 ÷ 6 = 2
