Addition and Subtraction
Addition:- Addition can explain by following example
Lets ram has 2 apple and john has 3 Apple
So if ram gives all 2 apple to john then john will have total 2+3=5
i.e. 5 Apple.
So addition means 2+3=5
Addition method on number line
lets say we have to add 2 and 3
then draw number line
—1—2—3—4—5—6—7—8-
So after 2 on the no. line we have to add 3, so after 2-3, 3-4 and 4-5 so after 3 interval or addition of 3 on 2 we get 5.
Subtraction: Subtraction is loosing of quantity.

Subtraction: Subtraction is loosing of quantity.
Lets say amy has 5 mangoes and she gives 2 mangoes to john then amy will now remaining 5-2=3 mangoes.
On the number line:
—1—2—3—4—5—6—7—8—9—10-
On the number line if the 5-4 and 4-3 so the total reduction after 2 interval is 3.
