Question

1. Calculează în două moduri.
4 x (6 + 3) =
(9-5) x3 =
6 x (5-2) =
(8 + 2) x 7 =​

Answer 1

Răspuns:

I) 4 × ( 6 + 3 ) = 4 × 9 = 36

II ) ( 4 × 6 ) + ( 4 + 3 ) = 36

24 + 12 = 36

I ) ( 9 - 5 ) × 3 = 4 × 3 = 12

II) ( 9 × 3 ) - ( 5 × 3 ) = 12

27 - 15 = 12

I) 6 × ( 5 - 2 ) = 6 × 3 = 18

II) ( 6 × 5 ) - ( 6 × 2 ) = 18

30 - 12 = 18

I) ( 8 + 2 ) × 7 = 10 × 7 = 70

II) ( 8 × 7 ) + ( 2 × 7 ) = 70

56 + 14 = 70
