I've been bored during our math classes at high school-so I decided to create my own math question. I've been brewing on it for a while-but I haven't gotten an answer. Probably just my tired brain telling me to stop, but I really want an answer and the working out.
If anyone wants the question it is:
You have the numbers from 1-100 listed down. How many numbers do you have to remove from the list so that the remaining product of the numbers has a remainder of 4 when divided by 5? What are the numbers?
