Answer 1

a)515+515:5-515x0=
=515+103-0=412

b. (286-7x7):3+(12x8:2+4:4)=
= (286-49):3+(48+1)=
= 237:3+49=
=79+49=128

c. 1098+700:100-(890:10+18)x0=
= 1098+7-0=
=1105

d. 119x(917:7)+5234-209=
= 119x131+525=
= 119x131+525=
=15589+525=16114

e.[675+234x4-(876:4+7434:9)]x1000=
=[675+936-(219+826)]x1000=
=(1611-1045)x1000=
=566x1000=566000


f.5x[(0:85+85:85)+987:7-142]+85x11=
=5x[(0+1)+141-142]+935=
=5x(1+1)+935=
=5x2+935=
=10+935=945


g. 9+10x[365+10x(60+60:5)]:5=
= 9+10x[365+10x(60+12)]:5=
= 9+10x(365+10x72):5=
= 9+10x(365+720):5=
= 9+10x1085:5=
= 9+217=
=226
