Question

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

Answer 1

Răspuns:

4 × ( 6 + 3 ) = 4 × 9

= 36

4 × ( 6 + 3 ) = ( 4 × 6 ) + ( 4 × 3 )

= 24 + 12

= 36

6 × ( 5 - 2 ) = 6 × 3

= 18

6 × ( 5 - 2 ) = ( 6 × 5 ) - ( 6 × 2 )

= 30 - 12

= 18

( 9 - 5 ) × 3 = 4 × 3

= 12

( 9 - 5 ) × 3 = ( 9 × 3 ) - ( 5 × 3 )

= 27 - 15

= 12

( 8 + 2 ) × 7 = 10 × 7

= 70

( 8 + 2 ) × 7 = ( 8 × 7 ) + ( 2 × 7 )

= 56 + 14

= 70
