Question

ayuda plis lo necesito para ahorita con procedimiento :)​

Answer 1

a- 8-6+5-7= 2+5-7=7-7=0

b-5×12÷6÷2=60÷6÷2=10÷2=5

c- 3+(1+5)÷2= 3+6÷2=3+3=6

d-((25-15)÷5+(38-18)÷2)÷3+28= ((10)÷5+(20)÷2)÷3+28= (2+10)÷3+28=12÷3+28=4+28=3

e- (12-(8-5)×(5+(6-4))-3+(8-6)=(12-(3)×(5+2)-3+2)=

9×7-1= 62

f- 5-(7-2-(1-9)-3+12)+4= 5-(5-(-8)+9)+4=5-(5+8+9)+4=5-22+4 =-13

g- 1-(-3+6+1)-(4-(6-3+1)-2)= 1-(4)-(4-(4)-2)= 1-4+2=-1

h-28-(21-(12-3)-7)=28-(21-9-7)= 28-(5)=23

i-6-(-9+7-1)-(3-(-5+4+6)-1)=6-(-3)-(3-(5)-1)= 6+3+3=12

j- -8-(6-(-3+7)-6)+4= -8-(6-(4)-6)+4= -8-(-4)+4= -8+4+4= 0

k- 7+3×(12-7)=7+3×(5)=7+15=22

l-7+3+18÷3=10+6=16

m- 5×(4-2)²+1²×(2³-5)²= 5×(4)+1×(8-5)²= 20+1×(9)= 20+9=29

n- 2×(9-2×3)+(8-2)×(5²-6×3)= 2×(3)+(6)×(25-18)= 6+6×7=6+42=48

o- (3²-2³)× (5+2×3)-11+25x2= (9-8)×(11)-11+25×2=

11-11+50=50
