A-)  15+8*3+2(elv2)           B-) 5(elv3)+16*(-5)+2   D-) -18-5(-13)+4(elv2)                            
15+8*3+4                                125+16*(-5)+2                    18-65+4(elv2)
15+24+4                                    125+80+2                             18-65+16
15+28= 43                                  205+2= 207                          -47+16= -31

E-) 25*4+13*9                      F-) 44-8(elv2)-132              G-)86+13*7-140
100+117=217                            44-64-132                           86+91-140
                                                     -20-132= -152                  177-140=37
H-) -28-43+75*5(elv2)           I-) 7(elv2)+3*9-64           J-)-35-86-124-10
 -28-43+75*25                               49+3*9-64                    -121-134= -255
-28-43+75*25                              49+27-64
-28-43+1875                                   76-64=12 
-71+1875=1874
