Question from Wica, a student:

Hello,

So happy I found this site. I am having problems with bases. My question is :
Please perform the subtraction between two number over different bases :
A. (5874)base 12 - (216)base 9
B. (216)base 9 - (5874)base 12

Hi,

I would first convert $216_9$ to base 12 and then perform the subtraction. There is an example of subtraction in my response to a question from Janelee.

Write back if you need more assistance,
Penny
