I never was very good at math in any grade I was in. Beyond the basics of adding and subtracting, anyways.
I was forced to learn a lot of math recently though because it was part of my first semester of computer school... for academic reasons. It's not like I'm coding binary, so 1+2+15+-50(4x3)+-2 really isn't necessary!
I found that I'm am capable of learning this stuff, but it hurts my brain very much and I usually end up with a migraine and feel like crying after I've done a worksheet or test. Most math is useless to us normal people. Let the scientists and astronauts learn it
