You need to remove two matchsticks to make the below equation true. Can you do it ?

I am a prime number.
The double of myself is equal to the square of me.

which number am I?

Only one colour, but not one size,
Stuck at the bottom, yet easily flies.
Present in sun, but not in rain,
Doing no harm, and feeling no pain.
What is it?

As a whole I am both
safe and secure.

Behead me and I become
a place of meeting.

Behead me again and I am
the partner of ready.

Restore me, and I become
the domain of beasts.

What am I?

Jenifer is learning to drive her car. She went down a one way lane and in the wrong direction. But she do not break any law.

My sock drawer has 26 blue socks, 13 pink socks, 33 green socks, and 12 red socks, how many socks would I have to pull out in the dark to be sure I had a matching pair?
