Learn Class 1 Math - Addition

Basic Addition

Addition means keeping things together. For addition we put ‘+’ sign, and it is known as ADD/PLUS sign.

Example 1:We have 4 Blue balls and 3 red balls.
Total number of balls = 4 + 3 = 7 balls
So, we have total 7 blue and red balls

Example 2:We have 6 white boxes and 3 green boxes.
Total number of boxes = 6 + 3 = 9 boxes
So, we have total 9 white and green boxes.

Addition Order

During the addition, if we change the order of numbers then the answer does not change.

Example:Addition of 3 yellow balls and 4 green balls (3 + 4 =7)

Addition of 4 green balls and 3 yellow balls(4 + 3 =7)

Adding Zeros

When we add zero to a number, the answer remains same.

Example 1:5 stars + 0 stars = 5 stars

Example 2:3 smileys + 0 smileys = 3 smileys

Story Sum

Example:Ram has 5 chocolates and Sita has 4 chocolates. What is the total number of chocolates they both have?

Number of chocolates Ram has = 5

Number of chocolates Sita has = 4

So, Ram and Sita both have 5 + 4 = 9 chocolates.
