C. 7×9 = 9×7 = 63

D. 26 × 24 = 24× 26 = 624

2. A. (7+8)+9 = 7+ (8+9) = 24

B. (5+6)+3 = 5+(6+3) =14

C. (2×7)×9 = 2×(7×9) = 126

D. (21×24)×19 = 21×(24×19) = 9.576

3. A. 4×(5+7) =(4×5) + (4×7) = 20 + 28 =48

B. 3×(8+10) = (3×8) + (3×10) = 24+30 =54

C. 25 ×(25-15) = (25×25) – (25×15) = 625 – 375 =250

D. 13× (17+14) = (13×17) + (13×14) = 221-182 = 39
