dividing problem

hi,

ive created a program that can add, subtract, multiply and divide. The problem i have is that in the dividing section of the program it develops the numbers randomly and therefor most of the time the numbers created to divide dont match.

eg, 17 / 5

is there a way i can create numbers that match each other and can be divided like 10 / 2 = ?

cheers.

make two random integers, then multiply one by the other then use the result as the number that gets divided
