Question

Calculează respectând ordinea operaților:
(4+3)×7=

b) 7×(6+4)=

C)(8+7)×9=

D) (2+9)×6

E) (10-3)×6=

f) (10-3)×6=

Answer 1

Intotdeauna parantezele sunt primele care se rezolva : 7 ori 7 =49, 7 ori 10=70, 15 ori 9 =135, 11 ori 6 = 66, 7 ori 6 =42, 7 ori 6=42.

Answer 2

$a) \: (4 + 3) \times 7 = 49$
$b) \: 7 \times (6 + 4) = 70$
$c)(8 + 7) \times 9 = 135$
$d)(2 + 9) \times 6 = 66$
$e)(10 - 3) \times 6 = 42$
$f)(10 - 3) \times 6 = 42$
