Starting with my first period. Consumers math is a class meant to teach us valuable mathematical skill like how to do your taxes, and understanding and calculating your credit score. We didn't really do projects this semester which is fine. some challenges I've faced during this semester in this class is generally staying awake which isn't typically a problem but sometimes I do fall asleep in class and fall slightly behind but it's never nothing to serious. The 21st century skill I used is financial, economic, and business literacy. how I used said skill is by combining my prior and new found knowledge to solve complex finical and economical problems.
