s-> 49.000
p->49.999
t->200.000×3=600.000
m-12356+18644=49000
notam primele două operatii cu x
x+18644=49000
x=49000-18644=30356
m-12356=30356
m=30356+12356
m=42712( metoda notarii)
n+30500-10999=49999
notam primele două operatii cu x
x+10999=49999
x=49999-10999
x=39000
n+30500=39000
n=39000-30500
n=8500( metoda notarii)
300005+p+200995=600000
p=600000-200995-300005
p=399005-300005
p=99000 ( metoda mersului invers)
