Kak tlgin sya banget

A=120 B= -378 C=720 D=24000 E=54

a. -8 x (-32 + 17) = -8 x -15 = 120
b. [-12-(-30)] x (-21) = [-12 +30] x (-21) = 18 x (-21) = -378
c.9 x (-4 x 5) x (10-14)= 9 x (-20) x (-4) = 9 x 80= 720
d.(-15+7) x 50 x [5 x (-12)]= (-8) x 50 x (-60) = (-8) x (-3.000)= 24.000
e.[14 x (-7)] + [-19 x (-8)]= (-98) + 152= 54

ingat!! utamakan krjakan soal yang berada dalam kurunh terlebih dahulu..

smoga brmanfaat.
