j) (-64):(+2)=

Answer 1

a) 40-10-8 = 22
b) -30-7+18 = -19
c) -1-2+29 = 26
d) -10-18 = -28
e) 6.10 = 60
f) -2.30 = -60
g) -15.4 = -60
h) -20/-4 = 5
i) -15/5 = -3
j) -64/2 = -32

Answer 2

a) 40-10-8 = 22
b) -30-7+18 = -37+18 = -19
c) -1-2+29 = 26
d) -10-18 = -28
e) 6 x 30 = 180
f) -2 x +30 = -60
g)  -15 x +4 = -60
h) -20 / -4 = +5
i) -15/+5 = -3
j) -64 / +2 = -32
