"Trinity University Engineering Grad (Math through Cal, and Chem)"
...am 23 years old and I graduated from Trinity University with a degree in Engineering Science (with a concentration in Chemical Engineering). Just by being in this particular program (actually received a minor in Mathematics) I know all sorts of high school math backward and forward, and can explain concepts from pre-algebra
all the way to Calculus...
10+ subjects, including algebra 1 and algebra 2
