16. Calculează:
(84 - 7x 8) + 9x 7 =
100 - ( 6x6 - 3x8
(42 + 6 x 9) - (5x5 + 9x 3) =
54 + (76-7x4) + 8 x 9 =
(6x8) - (43-6 x 4) =
(130 - 9 x 9 +5 x 4) - 7x5+3 x 6) =​

Answer 1

Răspuns:

1. (84-7×8)+9×7=

84-56+63=

28+63=91

2. 100-(6×6-3×8)

100-(36-24)

100-12=88

3. (42+6×9)-(5×5+9×3)=

42+54-25+27=

96-52=44

4. 54+(76-7×4)+8×9

54+76-28+72

130-100=30

5. (6×8)-(43-6×4)=

48-43-24=

5-24=-19

6. (130-9×9+5×4)-7×5+3×6=

(130-81+20)-35+18

(49+20)-53

69-52=16
