This week, the grade 10 students continued their unit on solving linear systems with an exploration of matrices. They learned how to simplify matrices with Gauss-Jordan Elimination, as well as how to calculate and apply determinants to solve matrices with Cramer’s Rule. Next week, they will continue their study of matrices by examining their applications for other unique systems.
This week, the grade 9 math class continued their study of money, exploring the intricacies of compound interest. Students learned about converting between nominal and effective interest rates, calculating changing compounding periods, as well as instantaneous compounding. They will soon go on to study logarithms.
