Answer 1

45+20:4-3x5= 45+5-3x5=50-15=35
(10+13)+(36:9-21:7)= 23+(4-3)=23+1=24
164+(10-9:9-5x10)= 164+(10-1-50)=164+(9-50) = Nu se poate.
5x(10:10x10)+(8x3-23)= 5x(1x10)+(24-23)=5x10+1=50+1=51
48+(103-100)x9+(24:3x0)= 48+3x9+(8x0)=48+27+0=75.
(25:5-7:7)+(36:9+8x0)=(5-1)+(4+0)=4+4=8.
815-24:6x2=815-4x2=815-8=807.
21-21:7x(4-5:5)=21-3x(4-1)=21-3x3=21-9=12.

Sper ca te-am ajutat.

Answer 2

45+5-15=50-15=35 (10+13)+(36:9-21:7)=23+(4-3)=23+1=24
