# Math Puzzle - What am I?

I am X. I was roaming around some place and found another X. We got attracted. Got into some operation and generate Y.

At first Y is 0

Me and my X got together now and went to roam the places.

We are now 2X

We found the group of X with the same number of members as ours and also got into some private operation and got another Y.

We have Y+1

Now, we all X's got together and the same process happened, got Y and again went around with all the X's.

Now tell me What am I?

You are

a vector, roaming somewhere such as the plane.

At first Y is 0

You are aligned with and opposite to the other X

We are now 2X

You are aligned with and in the same direction as the other X

We found the group of X with the same number of members as ours and also got into some private operation and got another Y.

You’ve engaged in matrix operations, maybe multiple times.
