Question

Calculează respectând ordinea efectuați operantilor:
8×(2+8)+36:4=
57-6×7)×3:9+2=
4×(25-10×2)+6×(32:8)=

Answer 1

8 × ( 2 + 8 ) + 36 : 4 =

8 × 10 + 9 =

80 + 9 = 89

( 57 - 6 × 7 ) × 3 : 9 + 2 =

( 57 - 42 ) × 3 : 9 + 2 =

15 × 3 : 9 + 2 =

45 : 9 + 2 =

5 + 2 = 7

4 × ( 25 - 10 × 2 ) + 6 × ( 32 : 8 ) =

4 × ( 25 - 20 ) + 6 × 4 =

4 × 5 + 24 =

20 + 24 = 44
