112x (-7) + (-16): (-2)...(-15+(-3)) - 7 X (-4):4

112x (-7) + (-16): (-2)…(-15+(-3)) – 7 X (-4):4

Jawaban:

1. -76

2. 19

Penjelasan dengan langkah-langkah:

$12 times ( - 7) + ( - 16) div ( - 2) = \ - 84+ 8 = \ - 76$

$(15 + ( - 3)) - 7 times ( - 4) div 4 = \ (15 - 3) - 7 times ( - 4) div 4 = \ 12 - 7 times ( - 4) div 4 = \ 12 + 28 div 4 = \ 12 + 7 = \ 19$
