1. Calculează:
a) (8 x 3): 2 + [16 (14 +46): 10 + 175) =
(7 x 6): 3+ [80 x (50 +30): 10 +312) =
(5 x 8) : 4+ [25 Ⓡ (76 + 24): 10 - 184] =
b)
246 : 2 - 3 * 5 6+ [42: (7 + 14) + 5) =
187 x 5 - 9:38+ [70: (14 ~ 5) +9] =
128 x 4-6: 2 x 9 + [48: (12 x 2) + 7) =​

Answer 1

Explicație pas cu pas:

a) (8 x 3): 2 + [16 (14 +46): 10 + 175) =

24 : 2 + ( 16 x 50 : 10 + 175)=

12 + ( 16 x5 + 175) =

12 + (80+ 175)=

12 + 255 = 267

(7 x 6): 3+ [80 x (50 +30): 10 +312) =

42 : 3 + ( 80 x 80 :10 +312)=

14 + ( 80 ×8 + 312)=

14 + ( 640 + 312)=

14 + 952 = 966
