Explicație pas cu pas:

1.8x(23+14)=8x37=296

8x(23+14)=8x23+8x14=184+112=296

2.(123+12)x3=135x3=405

(123+12)x3=123x3+12x3=369+36=405

3.(120-16)x4=104x4=416

120x4-16x4=480-64=416

4.5x(325-250)=5x75=375

5x(325-250)=5x325-5x250=1625-1250=375

5.(42+18)x16=60x16=960

(42+18)x16=42x16+18x16=672+288=960

6.11x(32-15)=11x17=187

11x(32-15)=11x32-11x15=352-165=187

7.15x(85-29)=15x56=840

15x(85-29)=15x85-15x29=1275-435=840
