Question

Ex 3 Calculează in doua moduri.

Answer 1

8×(23+14)=8×37=296

(123+12)×3=153×3=465

(120-16)×4=104×4=416

5×(325-250)=5×75=375

(42+18)×16=60×16=960

11×(32-15)=11×17=187

15×(84-29)=15×55=825

Mai sus este primul mod

8×(23+14)=184+112=296

(123+12)×3=184+112=465

(120-16)×4=480-64=416

5×(325-250)=1625-1250=385

(42+18)×16=672+288=960

11×(32-15)=352-165=187

15×(84-29)=1260-435=825

Iar asta este al doilea mod!!!!

SUCCES!!!!!
