Math and Trading

I am somewhat new to trading and have been successful using a basic IT Cross strategy. I have posted a chart below for further reference.

However, I have never been very good at math. This strategy uses zero math skills. The furtherest I made it was pre calc. How much does math play a roll in trading? Should I be studying more math and learning new techniques of because I am just using technical analysis does it not matter?
