a) -2-3×5 = -2-15 = -17
b) (-8)÷4-2 = -2-2 = -4
c) 12÷(-2)-(-3) = -6+3 = -3
d) (-2)³×3-25 = -8×3-25 = -24-25 = -49
e) (-15)÷3-5×(-1) = -5+5 = 0
f) 3×(-7)-7×(-2) = -21+14 = -7
g) 6×(-4)+5×(-9) = -24-45 = -69
h) (-18)÷9-(-27)÷(-1) = -2-27 = -29
i) 24-36/4 -7 = -3-7 = -10
j) -9-6/-3 ×(-4) = 5×(-4) = -20
k) -9+5×(-11)/4 = -64/4 = -16 (nie widać dalszej części działania)
l) 4× -1-3/-2-3 = 4×4/5= 16/5 = 3 1/5
