Answer 1

Answer: 1. a) (-6)(-2) = 12(-2) = -24(-1) = 24

b)
`(64)/(8)`=
`(8)/(1)`=8

c) (-5) + (-6) = -5 - 6= -11

2. a) +10°C

b) -6m

c) -100m

d) +5000

3. a) 56-2(20+12÷4x3-2x2) + 10

=> 56 - 2[(20) +(12÷4)3 - (2x2)] + 10

=> 56 - 2[(20) + 3(3) - (2x2)] + 10

=> 56 - 2[20 + 9 - 4] + 10

=> 56 - 50 + 10

=> 16

b) 3 + 6(5+4) ÷ 3 - 7

=> 3 + 6(9) ÷ 3 -7

=> 3 + 54 ÷ 3 -7

=> 3 + 18 - 7

=> 14

c) 2[2 + 2[39 - 2(17 + 2)]]

=> 2[4[39 - 2(19)]]

=> 2[4[37(19)]]

=> 2[2812]

=> 5624

4. a)
`(2)/(5)` b) 45
`(2)/(3)` c) 13
`(6)/(7)` e) 2
`(1)/(2)` f) 2
`(1)/(2)` g) 31
`(1)/(2)`

5. a) 19
`(17)/(40)` b) 45
`(2)/(3)` c) 13
