Explicație pas cu pas:
A)a=234.567
b=58.954
a+b=234.567+58.954=293.321
a=?
b=360.847
suma lor=985.763
985.763-360.847=624.916(a)
a=135.854
b=?
suma lor=458.243
458.243-135.854=322.389
B)a=535.678
b=253.704
a-b=535.678-253.704=282.974
a=709.509
b=?
diferenta lor= 380.600
709.509-380.600=328.909
a=?
b=37.869
diferenta lor=28.608
37.869+28.608=68.477
