Calculați:
1) 5-3=2
2) (-15)+(-11)= -15-11=-26
3) (+10)+(-25)=+10-25=-15
4) 9-11+(-8)-(-2)=9-11-8+2=-2-8+2=-10+2=-8
5) (-2)+6+(-1)+(-3)+3+0= -2+6-1-3+3+0= 4-1-3+3+0=3-3+3+0=0+3+0=3+0=3
6)|-5|-|-6|+|3+4|=5-6+7= -1+7=+6
7) (-20+3)-(-20-5)+(-5-3)=-17-(-25)+(-8)=-17+25-8=+8-8=0
8)13-[-2+5-(-4+16)-2]= 13- (-2+5-12-2)= 13- (+3-12-2)=13-(-9-2)=13+11=+24
