Answer 1

a ) 92-13-39 = 79-39 = 40
46 - (26+13) =  46 - 39 = 7 
68 - 13 - 25 = 55-25=30

b) 57+16-20+4= 73-24=49
94-34+17-17=60+0=60
280-50+52=230+52=282

c)   * = razy
5*17*2=85*2=170
4*25*12= 100*12=1200
15* 4 : 6 = 60 : 6 = 10

d) 140:7:4=20:4=5
250:5:2=50 : 2 = 25
100:20*7=5*7=35

Answer 2

A) 92-13-39  = 79 - 39 = 40

b)57+16-20+4  = 57 + 20 - 20 = 57

c) 5razy 17 razy 2 = 17 razy 10 = 170

d)140:7:4 = 20 : 4 = 5

46-(26+13) = 46 - 39 = 7

94-34+17-17 = 94 - 34 = 60

4 razy 25 razy 12 = 100 * 12 = 1200

250:5:2 = 50 : 2 = 25

68-13-25 = 68 - 38 = 30

280-50+52 = 280 + 2 = 282

15 razy 4:6 = 60 : 6 = 10

100:20Razy7 = 5 razy 7 = 35
