+343 What is the symbol $ ?
Why is 15$ and not 15.What is the difference?
Thank you.
+9485 It is leftover from when the asker copy and pasted the question. Other sites use $'s to enclose latex, but this site does not. The dollar sign shouldn't be there.
+343 Aha ok thank you I was wandering if it was a mathematical symbol witch I didn't know.
