Complete 10 Times Table.
1 10 is 10 5 10 is 50 9 10 is 90
2 10 is 20 6 10 is 60 10 10 is 100
3 10 is 30 7 10 is 70 11 10 is 110
4 10 is 40. 8 10 is 80 12 10 is 120

a) 90 – ( 30 – 20) = 90 – 10
= 80
90 – 30 – 20 = 60 - 20
= 40
b) 100 – (60 + 10) = 100 – 70
= 30
100 - 60 + 10 = 40 + 10
= 50
c) 135 – (30 + 5) = 135 – 35
= 100
135 – 30 – 5 = 105 – 5
= 100
d) 70 + (40 – 10) = 70 + 30
= 100
70 + 40 – 10 = 110 -10
= 100

6000 + 10 + 2 = 6012
5000 + 9 = 5009
4000 + 400 + 4 = 4404
2000 + 20 = 2020
