Answer 1

№1

a) 4 × (-6) = -24
b) -21 × (-5) = 105
c) -8.4 × 5.7 = -47.88
d) 18 × (-6.5) = -117

№2

a) -18 / 3 = -6
b) -2898 / (-14) = 207
c) 22.23 / (-0.9) = -24.7
d) 0 / (-53) = 0

№3

a) 8m + 5p - 13m - p = -5m + 4p
b) x - ( 17 - x ) + (-x + 30) = x - 17 + x - x + 30 = x + 13
c) -6 (4 + a) + 8(a-6) = -24 - 6a + 8a - 48 = -72 + 2a

№4

a) (-3.2 - 4.9) × (-1.3 × 4 + (-1.6) × (-5)) = (-8.1) × (-5.2 + 8) = -8.1 × 2.8 = -22.68
b) (-1,42-(-3,22)):(-0,8)+(-6)*(-0,7)=1,8:(-0,8)+4,2=-2,25+4,2=1,95
