3. I am the amount left over when a number cannot divided equally. 4. I am the number that divided the dividend.

You're describing the concept of a remainder and a divisor! The remainder is the left-over part that doesn't fit into complete groups when dividing. For example, if you divide 10 by 3, you get 3 as the quotient, but 1 is left over, making 1 the remainder. On the other hand, the divisor is the number you're dividing by! Continuing with the previous example, 3 is the divisor because it's the number used to divide into 10. Knowing these terms can really clarify how division works in math!
