Question

Ma ajutati ,va rog frumos ,dau coronita!

Answer 1

a)

|-4|-|-5|+|4-8|=

4-5+|-4|=

4-5+4=3

b)

(-18+9)-(-23-6)+(-8-3)=

-9-(-29)-8-3=

9-29-8-3=9

c)

|8-16|+23-|16-20|-8=

|-8|+23-|16-20|-8=

8+23-|16-20|-8=

8+23-|-4|-8=

8+23-4-8=19

d)

45-[-13+26-(-18+35)-16]=65

-13+26=13

-18+35=17

13-17=-4

-4-16=-20

45-(-20)=65

e)

-{-36-[53+(-45+14)]-3}=45

-45+14=-31

-53+(-31)=-84

-36-(-84)=48

48-3=45

f)

-25+{-14-[-45+13-(-46)]}=

-45+13=-32

-32-(-46)=14

-14-14=-28

-25+(-28)=-53

g)

(1+2+3+...+205)+(-1-2-3-...-203)=2

1+2=3

3+3=6

-1-2=-3

-3-3=-6

205-203=2
