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
