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

MATH 
brandon,
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
