Step-by-step explanation:
ACTIVITY 1.1
1) 5(2) = 10
2) 7+6 = 13
3) 6-4 = 2
4) 3(11)+7 = 40
5) 5(7+0.5) = 37.5
ACTIVITY 1.2
1) 3.4 + 1.7 = 5.1
2) 3.5 + 1.7 = 5.2
3) 4.1 + 1.7 = 5.8
4) 5.3 + 1.7 = 7
5) 8.9 + 1.7 = 10.6
ACTIVITY 1.3
1) 2(2) + 7 = 11
2) 4(5) ÷ 2 = 10
3) (5+3) ÷ 2 = 4
4) (3+5) ^2 = 64
5) 2 + (3*5) = 17
ACTIVITY 1.4
1) 39-7 = 32
2) 35+4 = 39
3) 25 (5) = 125
4) 594 ÷ 6 = 99
5) 2(45) + 12 = 102
