SUBTRACT:

(1) (a) 6 – 1 = 5

(b) 9 – 8 = 1

(c) 8 – 3 = 5

(d) 9 – 6 = 3

(e) 7 – 2 = 5

(f) 10 – 7 = 3

(g) 9 – 1 = 8

(2) (a) 6 – 2 = 4

(b) 10 – 4 = 6

(c) 3 – 3 = 0

(d) 9 – 5 = 4

(e) 6 – 4 = 2

(f) 5 – 5 = 0

(g) 3 – 2 = 1

(3) (a) 8 – 4 = 4

(b) 10 – 8 = 2

(c) 9 – 9 = 0

(d) 6 – 0 = 6

(e) 5 – 2 = 3

(f) 4 – 3 = 1

(g) 7 – 5 = 2

(4) From 8 take away 5 = 8 – 5 = 3

(5) From 6 take away 2 = 6 – 2 = 4

(6) From 9 take away 7 = 9 – 7 = 2

(7) From 4 take away 4 = 4 – 4 = 0

(8) There are 4 ducks in the park. 3 have gone for swimming. How many are left?

Ans: 4 – 3 = 1

Hence, there is 1 duck in the park.

(9) There were 8 children in the amusement park. 3 of t hem were wearing hats. How many children were not wearing hats?

Ans: 8 – 3 = 5

Hence, 5 children were not wearing hats.
