a |-----|+343|
b |-----|               } 857.

857 - 343 = 514      ( 2 segmente egale)
514 : 2 = 257 (b)
257 + 343 = 600 (a)
Verificare : 600 + 257 = 857   ( suma)
                   600 - 257 = 343     ( diferenta).

a+b=857
a-b=343 rezulta ca a=b+343
a+b=857
b+343+b=857
2b+343=857
2b=857-343
2b=514
b=514:2
b=257
a=b+343
a=257+343
a=600
