Răspuns:

14) 3841

16) 30.900

19)53723, 53724, 53725, 53726, 53727, 53727, 53728

Explicație pas cu pas:

11) coloana 1: a-b 384-178325=205999

a+b 384324+178325=562649

coloana 2: 298744-b=11324

298744-11324=b

287420=b

a+b 298744+287420=886164

coloana 3: a-524128=123344

a=123344+524128

a=647472

a+b 647472+324123=1171595

coloana 4: 289324+b=574124

b=574124-289324

b=284850

a-b 289324-284850=4474

16)deci 67.243 + 123.321 + a = b

b - 12.873 = 184000+24582

b-12873=208582

b=208582+12873 de unde b rezulta 221455

acum vine 190555+a=221455

a=221455-190555

a=30900

19) aici 36438+17285=53723

36439+17285=53724

36440+17285=53725

36441+17285=53726

36442+17285=53727

36443+17285=53728

14) a+8543=12384

a=12384-8543

a=3841
