### New formula for squaring a no.[or may be old].

Hey I was just playing with nos. I found a formula to sq. A no. I.e.
(<n-1>squared)+(2n+1)
'n' here implies the no. You want to sq.

Hi;

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

This works if you know sq of no. Which lies before it just add 2xno.+1 to sq of no. Lying before the no.

You mean like this:

(2 * 6 + 1) + 6^2 = 49 which is 7^2?
