preciso urgente

Answer 1

Resposta:

a)-6+3+5=2

b)3-(-5)+(4-5+8-2)=

3-(-5)+5=

3+5+5=

10+3=13

c)-5+5x(-5)

-5-25=-30

d)-4-3=-7

e)21x6=126

f)-5

g)-(8x13)=-104

h)6-(3+1-10)+(-3)x5=

6-(3+1-10)-15=

6-(-6)-15=

6+6-15=-3

i)-5+4-(-10+3)=

-5+4-(-7)=

-5+4+7=6

j)2-(5x(-6)-6)+(2,4-10)=

2-(5x(-6)-6)+(-7,6)=

2-(-30-6)+(-7,6)=

2-(-30-6)-7,6=

2-(-30)-7,6=

2+36-7,6=

30,4   ou   $\frac{152}{5}$
