This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

I am like not really well informed about this but wasn't the square root symbol thingy (√ <- this one) always set to give the positive root? And the power of 1/2 would give both the positive and negative?
I had to look it up and it looks like you're right. If only my teacher had spent any effort at all explaining that.
Yes, it is positive, and power 1/2 is, too. Two solutions emerge from solving equations, even primitive ones, like x^2 = C.
