addition and Subtraction reLationSHiP

A number fact is a simple statement made up of
three different numbers. For example, 4 + 3 = 7

is a number fact.

Here, the three numbers used are 4, 3 and 7.

Latika: Add 4 and 5 in any order, the answer will
be the same. 4 + 5 = 9 same answer

or 5 + 4 = 9

Shreyas: We can have two subtraction facts for the above addition facts as

9 – 5 = 4 and 9 – 4 = 5

Mayank: It is a beautiful relationship between addition and subtraction.

To each addition fact there are two subtraction facts.
