Question

calcule: a) -5 -3.(-2)

b)|-11|

c)|7-4| + |4-7|

d)2+5.(-3)-(-4)

e)-11-2.(-3)+3

f)-8+3.[2-(-1)]

g)|2+3.(-2)| - |3+2.(-3)|

Answer 1

a) -5 -3. (-2)=
-5+6=1
b) -11 ou 11
c)|7-4|+|4-7|=
|3|+|-3|= 0
d)2+5.(-3)-(-4)=
2-15+4=9
e)-11-2. (-3)+3=
-11+6+3=-2
f)-8+3. [2-(-1)]=
-8+3. [2+1]=
-8+3. 3=
-8+9=1
g)|2+3. (-2)|-|3+2. (-3)|=
|2-6|-|3-6|=
|-4||+3|=-1

Answer 2

Resposta:

a) -5 -3. (-2)=

-5+6=1

b) -11 ou 11

c)|7-4|+|4-7|=

|3|+|-3|= 0

d)2+5.(-3)-(-4)=

2-15+4=9

e)-11-2. (-3)+3=

-11+6+3=-2

f)-8+3. [2-(-1)]=

-8+3. [2+1]=

-8+3. 3=

-8+9=1

g)|2+3. (-2)|-|3+2. (-3)|=

|2-6|-|3-6|=

|-4||+3|=-1
