a) -(-(-4)) * [8-(-5)*(-2)+(-4)*7]: [-(-4)+11]
b) -(-(-(-5))) +(-4) * (-12)- (-(-3)) * (-12): (-(-6))
c) -[-(-10+ 17)-8] : [-4+3* (-5)*(-2) : 10-2]+(-7)
Proszę o obliczenia jak można z góry dziękuje :D Dam naj:P

a) -(-(-4)) * [8-(-5)*(-2)+(-4)*7]: [-(-4)+11]=
-4*[8-10-21]:15=
-4*-23:15=
92:15=6,13
b) -(-(-(-5))) +(-4) * (-12)- (-(-3)) * (-12): (-(-6))=
5-48-3*-12:6=
5-48+36:6
5-48+6=
5-54=-49
c) -[-(-10+ 17)-8] : [-4+3* (-5)*(-2) : 10-2]+(-7)=
-[-(-1)]:[-4-15*(-2):10-2]+(-7)=
-1:[-4+30:10-2]-7=
-1:0.6-7=-5,33
