Holy moly, I forgot how hard math can be! I really feel for our youth who every year have to gear up for entrance, mid-terms, and final exams. If I had not known a math wiz who helped me extensively with my homework, I would not have made it through algebra, geometry, or trig, and I now only have a fuzzy idea of the rules (like the Pythagorean Theorem required to solve the above). I figured by now, one could use Siri to answer math questions, or at least the mega awesome MyScript calculator app (free). NOTE: Please do not try to use Siri or your iPhone/iPad during an exam, unless explicitly told you are allowed to do so by an authorized test administrator. If you are one of the unlucky few who are grinding through trig problems (or verb conjugation) these beautiful spring and early summer days, check out Play2Prep (free). It is designed to make getting ready for your next major exam fun and engaging. Mostly I found it to be quite ridiculously hard...but yeah, in a fun way I guess!
