Answer 1

Calculam dupa regulile urmatoare:
Prima data efectuam inmultirea/impartirea dupa care adunarea/scaderea.
12+6/2=12+3=15
25-8/4=25-2=23
64/8x3=8x3=24
5/10x7=0,5x7=3,5
36+21/7+15=36+3+15=57
64-35/5-32=64-6-32=56
36/4+9x3=9+27=36
27/3+81/9=9+9=18
25+24/6x3=25+4x3=25+12=37
12+36/9/2=12+4/2=12+2=14
50-80/1x0=50-80x0=50-0=50
36+25/5x1=36+5x1=36+5=41
