oblicz :
a) 12 -37 = 12 + ( - 37 ) =
b) ( - 3 ) - (-35) =
c) -4 + (-12 - 7 ) =
d) 3 - [ 2 x (-5)] - ( - 1 ) =
e) -13 + [ -2 - 6 : ( - 3) ] =
f) -3 - 5 - [ (-2) ³ - ( - 1 ) x 4 ] - (-2)
g) - 12 : ( - 6 ) - [ (-1) ⁴ - ( - 2) x 3 ]: ( -2 ) =
h) - ( -5 ) - ( 12 - 6 ) : ( - 3 ) + ( - 4 ) : 2 =
PROSZĘ O SZYBKĄ POMOC !!!

a) 12 -37 = 12 + ( - 37 ) = - 25
b) ( - 3 ) - (-35) = -3 + 35= 32
c) -4 + (-12 - 7 ) = -4 + (- 19)= -23
d) 3 - [ 2 x (-5)] - ( - 1 ) =3- (-10) +1= 3+ 10+ 1= 14
e) -13 + [ -2 - 6 : ( - 3) ] = -13+ [ -2 +2] = -13 + 0= -13
f) -3 - 5 - [ (-2) ³ - ( - 1 ) x 4 ] - (-2)= -3 -5 - [-8 - (-4)] = -3 -5 -(-4)= -8 + 4= -4
g) - 12 : ( - 6 ) - [ (-1) ⁴ - ( - 2) x 3 ]: ( -2 ) = 2 - [1- (-6)] : (-2)= 2- 7 : (-2)=
= 2 + 3 ½= 5 ½
h) - ( -5 ) - ( 12 - 6 ) : ( - 3 ) + ( - 4 ) : 2 = 5 - 6: (-3) + (-2)= 5 + 2 -2= 5
