# Stuck in Arithmetic Formatter

Tell us what’s happening:
I’m still getting all the errors.
Can someone help find the bug?

Challenge: Arithmetic Formatter

what do you get as errors? can you post them?

Yes, sorry i forgot to paste the errors, I edited now

this is the easy one
you are missing a character in your output string

yo7u have extra characters (spaces) at the end of each line

Great!
thanks i got it now.
i think it was just a bit difficult to see the errors, but as you put it in red and green was much easier haha

thanks!
