Answer 2

a)3•(4:2)=3•2=6

b)(3•4):2=12:2=6

c)5•(4+7)=5•11=55

d)(5•4)+(5•7)=20+35=55

e)7•(6-3)=7•3=21

f)(7•6)-(7•3)=42-21=21

g)(35+12)+6:3=47+2=49

h)38+(12+40:8)=38+12+5=55

i)(99-35)+24+6•6=64+24+36=124

j)27+27:9+(20:4:5+12)=27+3+5:5+12=27+3+1+12=43

k)28+(7•6-24:6)+14=28+42-4+14=80

l)33-3+(16:4:2•9+11)=33-3+4:2•9+11=33-3+18+11=59

m)25+(11+7•7)+(25-3•6)=25+11+49+25-18=92

n)56:7:2+(40:5:4:2+3)=8:2+8:4:2+3=4+2:2+3=4+1+3=8
