2.Calculați respectând ordinea operaţiilor a) 4 x ( 9 367 – 6 579 – 2 779 ) + 1 464 − 9 x 9 = b) (3 x 3) x ( 4 x 2)-6 x 7+ ( 3 x 3 ) x ( 3 x 3 ) = c) (2 x 9 +6x3+6x6-72) x 9 x 9 x 8 =​

Answer 1

Răspuns:

a) 4 × ( 9367 - 6579 - 2779 ) + 1464 - 9 × 9 = 1419

4 × ( 2788 - 2779 ) + 1464 - 9 × 9 =

4 × 9 + 1464 - 9 × 9 =

36 + 1464 - 81 =

1500 - 81 = 1419

b) ( 3 × 3 ) × ( 4 × 2 ) - 6 × 7 + ( 3 × 3 ) × ( 3 × 3 )=111

9 × 8 - 6 × 7 + 9 × 9 =

72 - 42 + 81 =

30 + 81 = 111

c) ( 2 × 9 + 6 × 3 + 6× 6 - 72 ) × 9 × 9 × 8 = 0

( 18 + 18 + 36 - 72 ) × 9 × 9 × 8 =

( 36 + 36 - 72 ) × 9 × 9 × 8 =

( 72 - 72 ) × 9 × 9 × 8 =

0 × 9 × 9 × 8 =

0 × 9 × 8 =

0 × 8 = 0
