Ian multiplied a number by 5. He then multiplied that product by 2. What digit is in the ones place of the final product?

zero!
when you multiply by five, you'll always get a number ending in 0 or 5. multiplying by two means if you get one ending in 5, it gets timesed by 2 and equals zero anyways
try it with any number
