Oblicz:
a) [(49+61):11]-60:12=
b) [(620-200) : 7]-15+3 do potęgi 2=
c) 3 x 90 - [90 x (81 - 68)] =
d) 4 do potęgi 3 + [5x32 - (3500 + 1400) : 70] =
To kolejność wykonywania działań jakby coś.

b) [(620-200) : 7]-15+3 do potęgi 2 = 420 : 7 - 15 + 9 = 60 - 6 = 54
c) 3 x 90 - [90 x (81 - 68)] = 270 - 90 * 13 = 270 - 1170 = -900
d) 4 do potęgi 3 + [5x32 - (3500 + 1400) : 70] = 64 + 160 - 4900 : 70 =
224 - 70 = 154
