Hi all,

my DS is doing an Athey paper in which one of the questions is as follows:

write the number 13 in base four.

Does anyone know the answer please? I know what it is I just don't know how to write it down!!!

Confused mum!

13 in base 4 is 31 - usually with a four written in subscript afterwards

Hi,

Thanks Guest55, I thought I was along the right lines but wasn't sure how to clarify it was base four and not just the number 31!!

Thanks
