Question

Działania na liczbach dodatnich i ujemnych.
Oblicz:
a) 10 - 6 + 8 =
10 - (6 + 8) =
b) 10 - 5 * 6 =
(10 - 5) * 6 =
c) 8 * 7 - 6 =
8 * (7 - 6) =
d) 24 : 6 * ( -2 ) =
24 : ( 6 : ( - 2)) =
e) -12 + 4 : 2 - 8 =
( -12 + 4 ) : 2 - 8 =
f) 11 - 8 : 4 - 10 =
(11 - 8) : (4 - 10) =

Answer 1

A)10-6+8=4+8=12

10-(6+8)=10-14=-4

b)10-5*6=10-30=-20

(10-5)*6=5*6=30

c)8*7-6=56-6=50

8*(7-6)=8*1=8

d)24:6*(-2)=4*(-2)=-8

24:(6:(-2))=24:(-3)=-8

e)-12+4:2-8=-12+2-8=-20+2=-18

(-12+4):2-8=(-8):2-8=-4-8=-12

f)11-8:4-10=11-2-10=11-12=-1

(11-8):(4-10)=3:(-6)=(-0,5)
