Zad.1
a) -(2*14-32)+(-2)*(1-5)=-(28-32)+(-2)*(-4)=-(-4)+8=4+8=12
b) 350:(14+11)+5*[(-2)+(-3)]=350:25+5*(-5)=14+(-25)=-11
c) [(-2)-(-40)]*[-3+10]=[(-2)+40]*7=38*7=266
d) [-7-14+5]:[(-2)*8+8]=16:[-16+8]=16:8=2
Zad.2
a) 24-36/4 -2* (-30)-(-52)/2=24-9-(-60)-(-26)=15+60+26=101
b)-9-6/3 - 4+(-3)/-5-(-6)=-9-2-4+0,6+6-15+6,6=8,4
c) -9-(-15)/3 + -7/4-5 - 3*(-7)=-9-(-5)+(-1,75)-5-(-21)=-9+5+(-1,75)-5+21=10,25
d) -9+5*(-11)/2 * 5-4* -1-9/-2-3=-9+(-55)/10-(-1)+4,5-3=-9+(-5,5)+1+1,5=-14,5+2,5=-12
Mam nadzieję, ze dobrze to policzyłam jeśli nie to sorki, ale się starałam. ;)
a) -(2*14-32)+(-2)*(1-5) = -60+8=52
b) 350:(14+11)+5*[(-2)+(-3)] = 14+(-25) = -11
c) [(-2)-(-40)]*[-3+10] = -42*7 = -294
d) [-7-14+5]:[(-2)*8+8] = -16:-8 = 2
Zad.2
a) 24-36/4 -2* (-30)-(-52)/2 = -12/6*11=6*11=66
b)-9-6/3 - 4+(-3)/-5-(-6) = -15+(-3):30=-25
c) -9-(-15)/3 + -7/4-5 - 3*(-7) = 2+(-1,75)-5+21 = 16,25
d) -9+5*(-11)/2 * 5-4* -1-9/-2-3 = 32*5+4-4,5-3 = 156,50
