Answer 1

Answer:

1. (a) 13 × 19 = 247

(b) 16 × 0 = 0

(c) 0 × 24 = 0

(d) (-31) × 5 = -155

(e) (-12) × (-13) = 156

(f) 15 × (-16) = -240

2. [23+(-17)]+(-19) = [23 - 17] - 19 = 6 - 19 = -13

3. (a) 35 ÷ (-7) = -5

(b) 75 - 38 = 37

4. (a) 18 ÷ (-6) = -3

(b) 34 ÷ 34 = 1

5. the integer = 96 × (-3) = -288

6. (a) (-142)+(-58)+200 = 200 -200 = 0

(b) 134x11+134x9 = 1,474 + 1,206 = 2680

7. 34 + 56 = 90

8. (a) 15 - 7 = 8

(b) -7-19 = -26

9. the perimeter of a square = 21 × 4 = 84 m
