Explicație pas cu pas:

8x (8 +2) + 36:4 = 8 × 10 + 9 = 80 + 9 = 89

(57 - 6x 7)* 3:9 +25 = (57-42) × 3 : 9 + 25 = 15× 3 : 9 + 25 = 45 : 9 + 25 = 5 + 25 = 30

4x(25 - 10 x 2) + 6 x (32:8) = 4 × (25 - 20) +6 × 4 = 4×5 + 24 = 20 + 24 = 44

a) 8×(8+2)+36:4=8×10+9=80+9=89

b) (57-6×7)×3:9+25=(57-42)×3:9+25=15×3:9+25=45:9+25=5+25=30

c) 4×(25-10×2)+6×(32:8)=4×(25-20)+6×4=4×5+24=20+24=44

Succes!!;)
