My class took a diagnostic test and we struggled with polynomials. Teachers decide to give a whole worksheet with adding and subtracting polynomials, the 2 concepts we struggle with with a mini lesson with polynomials easy to solve compared to multi billion step problems

As a student staying home, not attending classes, and doing school work from home. You are a life saver. I can finish my math assignments now, without any struggle, from not being in class when the teacher explained how to solve it.
