Teacher's Note: Teacher can ask a few more possible questions following the above example on subtraction concept and elicit the answers from the students.

Subtract

7 −3 = 4

2 −1= 1

5 −4= 1

9 −2= 7

8 −4= 4

3 −1= 2

6 −5= 1

Subtracting 1 from any number gives its preceding number.

9 – 1 = 8

5 – 1 = 4

8 – 1 = 7

4 – 1 = 3

Subtracting the preceding number from any number gives 1.

7 – 6 = 1

3 – 2 = 1

6 – 5 = 1

9 – 8 = 1
