Question

Математика 3к. 2час. учебник с.99 н.5

Answer 1

45-15*6÷18 = 45-90÷18 = 45-5 = 40
8+28÷7×16 = 8+4*16 = 8+64 = 72
56+4*8-20 = 56+32-20 = 68
(67-20)*3 = 47*3 = 141
(72-30)÷6 = 42÷6 = 7
7*(9+5) = 7*14 = 98
15*(14-9) = 15*5 = 75
0*27 = 0
0÷27 = 0
0+27 =27
27-0=27

Answer 2

45-15*6/18=10
8+28/7*16=72
25*3-15*4=60*4=240
56+4*8-20=460
(5-5)*5=141
(5-5)/5=7
5*(5+5)=98
5*(5-5)=75
5*5=0
5/5=0
5+5=27
5-5=27
