Answer 1

Răspuns:

(25+15):5= 40:5=8 modul 1

25:5+15:5=5+3=8 modul 2

(45+39):3= 84:3= 28

45:3+39:3= 15+13=28

(81-27):9=54:9=6

81:9-27:9=9-3=6

(16+28):4=44:4=11

16:4+28:4=4+7=11

(44+48):4=92:4=23

44:4+48:4=11+12=23

(45-20):5=25:5=5

45:5-20:5=9-4=5

(78-46):2=32:2=16

78:2-46:2=39-23=16

(96-48):3=48:3=16

96:3-48:3=32-16=16
