k)-3+4×(-2)-3×(-2)=

Answer 1

a) R: 11+(+8) = 11+8 = 19
b)R: 9-(-3+8) = 9-(+5) = 9-5 = 4
c) R: 16-(15-6) = 16-(+9) = 16-9 = 7
d) R: -8+(-2-3) = -8+(-5) = -8-5 = -13
e) R: -7 -(-6+4) = -7-(-2) = -7+2 = -5
f) R: -16-(6+4) = -16-(10) = -16-10 = -26
g) R: (-3-7) + (-4+8) = -10 + 4 = -6
h) R: (-3 +1) - (-6+2) = -2 - (-4) = -2 +4 = 2
i) R: -2+(3-8) - (-3+5) = -2 -5 - (+2) = -7 -2 = -9
j) R: 9 - 3×4 = 9-12 = 3
k) R: -3+4×(-2)-3×(-2) = -3+(-8)-(-6) = -3-8+6 = -11+6 = -5
