OpenStudy (mathmate):
How many ways you can fill the first (left) letter?
OpenStudy (ericwise):

There are no repetitions, so, as you said, it's easier that you think!
OpenStudy (ericwise):
the last can have 2, given that 3
OpenStudy (ericwise):
So we get: 3x3x2 !
OpenStudy (mathmate):
Do you have the answer? I think you're on the right track.
OpenStudy (ericwise):
18 possibilities :D

\(\color{blue}{\Large\checkmark}{Right, way~to~go!}\)
OpenStudy (ericwise):
Thanks @mathmate :D btw how to you get the fancy text?
OpenStudy (mathmate):
\color{blue}{\Large\checkmark}{Way~to~go!}
Add \) at the end, and \( at the beginning.
OpenStudy (mathmate):
If you right click and ask for the source of ANY fancy text, it will reveal all the secret if you choose Latex!
OpenStudy (ericwise):
oh awesome, thanks again :D
