There are lots of possible answers, so I will give you 3 examples: 1 and 500, 2 and 250, 10 and 50.
Multiply the first two numbers first. Then multiply the result with the third number.
1x51=51
396
The numbers are: -5 and 3
111 = 3*37
1500

what 2 numbers add to make five and multiply to make -36
Multiply the first two numbers first. Then multiply the result with the third number.
The question does not make sense. There are not 500 prime numbers but infinitely many!

Multiply them by 100 - as you would with even numbers. So 5, as a percentage is 5*100 = 500%
An infinite number of times. If you restrict yourself to whole numbers, 500 has 6 factor pairs.

i have no idea what it is but i think its something you multiply by itself and you will get the answer.
