In 3's multiplication table every next number is addition of 3 to its previous number.
The 3' s multiplication table is,
3, 3+3=6, 6+3=9, 9+3=12, 12+3=15, 15+3=18,.... so on.
1. 6×(3+2)÷10 = 3
Work:
3+2 = 5
6 × 5 = 30
30 ÷ 10 = 3
2. 12-(3×3)+11 = 14
Work:
3 × 3 = 9
12 - 9 = 3
3 + 11 = 14
3. (10×0.4) + (10×0.8) = 12
Work:
10 × .4 = 4
10 × .8 = 8
8 + 4 = 12
4.(8 ÷ 4)×(4-2) = 4
Work:
8 ÷ 4 = 2
4 - 2 = 2
2 × 2 = 4
5.8.5-10÷2 = 3.5
Work:
10 ÷ 2 = 5
8.5 - 5 = 3.5
6.18-(8÷2)+25 = 39
Work:
8 ÷ 2 = 4
18 - 4 = 14
14 + 25 = 39
