Jawaban:

1. A. (18+7)×4 =

25 × 4 = 100

15 + 8 times 25 \ 23 times 25 = 575 \ \ \ - 22 + 28 div ( - 7) - 15 times 4 = \ - 6 div ( - 7) - 60 \ - 6 div - 67 = 0.0895

Jawaban:

A. 100

B.215

C. -86

Penjelasan dengan langkah-langkah:

A.(18+7) x 4

=25 x 4

=100

B. 15 + 8 x 25

=15 +(8×25)

=15+200

=215

C. -22 + 28 : (-7) – 15 x 4

= -22 + (28:(-7)) – (15×4)

= -22 +(-4)-(60)

= -22-4-60

= -86
