Question

Oblicz.

a) -(-(-4))*[8-(-5)*(-2)+(-4)*7]:[-(-4)+11]

b)-(-(-(-5)))+(-4)*(8-12)-(-(-3))*(-12:(-(-6))

c)-[-(-10+17)-8]:[-4+3*(-5)*(-2):10-2]+(-7)

*- razy

prosze daje naj kompletnie nie wiem jak to zrobic :(

Answer 1

a) -(-(-4))*[8-(-5)*(-2)+(-4)*7]:[-(-4)+11 ] =

    -4*[8-10-28]:[15] = -4 * (-30) : 15 = 120 : 15 = 8

b)-(-(-(-5)))+(-4)*(8-12)-(-(-3))*(-12:(-(-6)) =

 5+(-4)*(-4)-3*(-12:6) = 5+16-3*(-2)= 5+16+6=27

c)-[-(-10+17)-8]:[-4+3*(-5)*(-2):10-2]+(-7) =

-[-(7)-8]:[-4+(-15)*(-⅕)-2]+(-7) = -[-15]:[-4+3-2]+(-7) = 15:(-3)+(-7) = (-12)
