How wonderful for you to offer your talents at math to help others.

Ugh, takes me back to my struggles through a year of calculus for my Computer Science minor along with my accounting major which needed calculus for the statistics. I was so bad at calculus that it kept me out of one position programming ballistics at the company I worked at which ended up being the end of my career at that point. The rest of math came easier, but I was never great at it.

Nice that is came easy for you. I find it interesting what classes are easy for us & the ones that end up being tough
