a. -8x(-32+17) =
-8x(-15) =
-120.
b. [-12-(-30)] x (-21) =
18x (-21) =
-378
c. 9 x (-4x5) x (10-14) =
9 x (-20) x (-4) =
-180 x (-4) =
720.
d. (-15+7) x 50 x [5 x (-12)] =
-8 x 50 x (-60) =
-400 x (-60) =
24.000
e. [14 x (-7)] + [-19 x (-8)] =
-98+152 =
54
f. -8-[-4 x 15] + [11 x (-7)] =
-8-60+(-77) =
-145
