Is it normal that i still count with my fingers?

My brother does this. He has a form of autism though.

You should get over it about the time you reach puberty.

It's a sign of a genius.

Yes it is.
For me it's like a puzzle, when doing mathematics' all the numbers seem to jumble up making it confusing.

This is a mandament: use a calculator

I say, "if you can't count on yourself, who can you count on?"
