selesaikan operasi berikut a.[ 12 + ( - 32 )] x 10 = b.[ 28 : 7 ] + [ 40 : 10 ] = c. ( 25 : 4 ) + ( 13 x 6 ) = pakai cara !!!

A. (-20) × 10 = -200
B. (28 : 7) + (40 : 10)
4 + 4 = 8
C. (25 : 4) + (13 × 6) =
6,25 + 78 = 84,25

a. [ 12 + ( - 32)] × 10
= ( 12 - 32) × 10
= -20 × 10
= -200
b. [ 28 ÷ 7 ] + [ 40 ÷ 10 ]
= 4 + 4
= 8
c. ( 25 ÷ 5 ) + ( 13 ×6 )
= 5 + 48
= 53

MAAF KALO SALAH :)
