Question

Aflati termenul necunoscut din operatiile de adunare:
12 431 + a = 195 034
694 005 - b = 451 237
369 + c - 561 + 583 - 504 = 372
735 + 569 - 673 +806 - d = 405
247 869 +302 130 - e = 313 254

23 219 + f = 277 040
g - 12 518 = 86 512
h + 458 - 651 + 492 - 608 = 361
849 + 150 - 736 + 904 - j = 504
k - 112 352 + 101 203 = 364 323

Answer 1

a=195034 - 12431 = 182603
b=694005 - 451237= 242768
c=372+504-583+561-369 = 485
d=735+569-673+806-405 = 1032
e=247869+302130-313254 = 236745

f=277040 -23219 = 253821
g=86512+12518 = 99030
h=361-309 = 52
j=1167-504 = 663
k=364323+112352-101203 = 375472
          

Answer 2

a)=277 040 -23 219 = 253 821 
b) = 95 005 +451 237 = 1145242
c)=369+c-1144-504=372
369+c-640=372
