Explicație pas cu pas:

1. (2+8)×3=2×3+8×3=15+15=30

2×7+2×5=2×(6+6)=2×6+2×6=12+12=24

3×9+5×9=2×(3+33)=9×8+0×0=36+36=72

(6+4)×5=4×5+4×25=60+60=120

2. (3+4)×9=7×9=63

(3+4)×9=9×3+9×4=27+36=63

(6+2)×5=8×5=40

(6+2)×5=5×6+5×2=30+10=40

7×(8+2)=7×10=70

7×(8+2)=8×7+7×2=56+14=70

8×(5+4)=8×9=72

8×(5+4)=8×5+8×4=40+32=72

7×(10-6)=7×4=28

7×(10-6)=7×10-7×6=70-42=28

(8-5)×4=3×4=12

(8-5)×4=4×8-4×5=32-20=12

4. a) 4+5=9 9×2=18

b)4×2=8 (fete) 5×2=10(baieti)

8+10=18
