This is a simple math question from my 9 year olds homework. Could someone
with a mathematics background explain the reasoning behind the alleged
correct answer for me? Because I just don't get it.
The question:
What is the last digit in the number 346?
She answered 6 and so did I. The correct answer is apparently 3. Why?
I've already written a note to the teacher requesting an explanation, but I
was hoping someone in the group could come up with something better than
"Because the book says so".
Thanks
Boyd.
