You don't. This is a flawed question, but the OP didn't help matters lol

The number 1 is not considered a prime number, so the digit in the 'ones' column is 2.

1 is not considered a prime #, by definition. That's why I think the last # is 2. As the poster above noted!

Divide 36 by 2, then by 4, then by 6. Seems to work, no?




I guess that would work if common core math says that both 36/4 and 36/6 both equal 9.

Can we all agree that the only thing that needs to be discussed is the "10,000s" part of the question? FFS, the rest is easy and I am fricking horrible at math.

Since the OP edited with additional information, my wife (a 5th grade teacher) says either there is an error in the question or OP/OP's child is missing/withholding information.

Prime number is only divisible by one and itself

Pretty sure, by definition, one is a prime

My 7th grade daughter wants to know how you come by the 4 in the 10,000s place?

One isn't prime according to a google search.

Just pulled out the kids mathbook, 6th grade. Prime # defined as a whole #, greater than one whose only factors are one and itself.

I like 4 as the first number because the sequence should yield 4.5, and 4 is literally the next number in the sequence.

But I've been pretty damn wrong this whole thread.
