5) po kolei
-12, -3, -3, 1/15, 70, -0.027, -0.009, -1300
6)
a) 10-6-8=-4, 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=1
d)24:6•(-2)= 4•(-2)=-8, 24:(6•(-2))=24:(-12)=-2
e) -12+4:2-8=-12+2-8=-18, (-12+4):2-8=
=(-8):2-8=(-4)-8=-12
f) 11-8:4-10=11-2-10=-1,. (11-8):(4-10)=3:(-6)=-1/2
7) a) 3/4-5•(2-7)=3/4-5•(-5)=3/4-(-25)=25 3/4
b) 3/2-(7-3)-10=3/2-4-10=-12 1/2
c) 4-(3-1,5)•2=4-1,5•2=4-3=1
d) (1 3/8+2):3+2=3 3/8:3+2= 27/24+2=
=1 3/24+2= 3 3/24=3 1/8
