REPEDE VA ROG !!! COROANA !!!

Answer 1

Explicație pas cu pas:

6 x (24 - 14 : 2) - 54 =

6.(24-7)-54

6.17-54

102-54=48

(100 - 35 + 45 - 15) x 7 + (90 - 9 x 8) =

(65+45-15).7+(90-72)

(110-15).7+18

95.7+18

665+18=673

32 : 4 + (72 - 36) : 9 + 6 x (16 + 24 : 4 ) =

8+36:9+6.(16+6)

8+4+6.22

8+4+132

12+132=144
