Question

Calculati:
(100-810:9)x3
27x9-42:3
59+6x3:9-(24-8x0)
(659-23x7)+455:7

Answer 1

Răspuns:

( 100 - 810 : 9 ) × 3 = 30

( 100 - 90 ) × 3 =

10 × 3 = 30

27 × 9 - 42 : 3 = 229

243 - 14 = 229

59 + 6 × 3 : 9 - ( 24 - 8 × 0 ) = 37

59 + 6 × 3 : 9 - ( 24 - 0 ) =

59 + 6 × 3 : 9 - 24 =

59 + 18 : 9 - 24 =

59 + 2 - 24 =

61 - 24 = 37

( 659 - 23 × 7 ) + 455 : 7 = 563

( 659 - 161 ) + 455 : 7 =

498 + 65 = 563

Answer 2

Răspuns:

(100-90)x3=10x3=30, 243-14=229, 59+18:9-(24-0)=59+2-24=61-24=37, (659-161)+65=498+65=563.
