Me ajudem pfv :)

Answer 1

A)
= 25-(-8)×(+2)
= 25 + 8 . 2
= 25 + 16
= 41

b)
= 12 - (-6) × (+2)
= 12 + 6.2
= 12 + 12
= 24

c)
= 2.(-13) + 3.(-8) - 7.(-7)
= - 26 - 24 + 49
= - 50 + 49
= - 1

d)
= (-3).(+9) - (- 24)
= - 27 + 24
= - 3

e)
= 5.(- 8) - 3.(+10) + 63
= - 40 - 30 + 63
= - 70 + 63
= - 7

f)
= - 20 - 2.(-17) + (-12).(+4)
= - 20 + 34 + (-48)
= 14 - 48
= - 34

Answer 2

a)25-(-8)×(+2)

25 - (-16)
25 + 16
41

b) 12-(-6)×(+2)

12 - (-12)
12 + 12
24

c) 2×(-13)+3×(-8)-7×(-7)

-26 -24 + 49
-50 + 49
-1

d) (-3) . (+9) - (-24)

-27 + 24
-3

e)5×(-8)-3×(+10)+63

-40 -30 + 63
-70 + 63
-7

f)-20-2×(-17)+(-12)×(+4)

-20 + 34 + (-48)
-20 + 34 - 48
-68 + 34
-34
