Question

6. Calculează:
(84 - 7 x 8) + 9 x 7 =
(6 x 8) -(43-6 x 4) =
(42 + 6 x 9) -(5 x 5 + 9 x 3) = 100 - (6 x 6 + 3 x 8) =
54 + (76 - 7 x 4) + 8 x 9 =
(130 - 9 x 9 +5 x 4) -(7 x 5 + 3 x 6) =​

Answer 1

Răspuns:

Explicație pas cu pas:

(84 - 7 x 8) + 9 x 7 = (84-56)+63=28+63=91

(6 x 8) -(43-6 x 4) = 48-(43-24)=48-19=29

(42 + 6 x 9) -(5 x 5 + 9 x 3) = (42+54)-(25+27)=96-52=44

100 - (6 x 6 + 3 x 8) = 100- ( 36+24)=100-60=40

54 + (76 - 7 x 4) + 8 x 9 = 54+ (76-28)+72=54+48+72=174

(130 - 9 x 9 +5 x 4) -(7 x 5 + 3 x 6) =​ (130-81+20)-(35+18)=69-116= -47

Answer 2

Răspuns:

(84-7×8)+9×7=(84-56)+63=28+63=91

(6×8)-(43-6×4)=(48)-(43-24)=48-19=29

(42+6×9)-(5×5+9×3)=100-(6×6+3×8)=100-(36+24)=100-60=40

54+(76-7×4)+8×9=54+(76-28)+72=54+48+72=174

(130-81+20)-(35+18)=69-53=16

Sper că team ajutat!!!!
