Answer 1

Explicație pas cu pas:

a) 90 -(37+5):6=

90 - 42:6 =

90 - 7 = 83

100 - (35+21):8=

100 - 56:8=

100 - 7= 93

102 - (19+8):9=

102 - 27:9=

102 - 3 = 99

b) (24+8):4+(36+18):6=

32:4+ 54:6= 8+9= 17

(35 + 15): 5+ (36 + 18): 9 =

50:5 + 54:9= 10+ 6= 16

(81 + 18): 3+ (42 +24) : 6 =

99:3 + 66:6= 33 + 11 = 44
