New to Glasses – Dr said 20/20 vision but astigmatism

Just looking for a bit of advice.

The doctor said that I have 20/20 vision but that glasses would help me.

My prescription is below. I am so confused as to the sphere, cylinder, axis stuff. She advised that I have an astigmatism but I'm wondering how bad of one.

Also wondering if people here think it would be worth the $ to get glasses with my exam results.

Thanks in advance to any replies!
