Avoid these common algebra mistakes and stop throwing away marks on homework’s, assessments and exams. Never waste these marks again!
The first thing I check with all of my students is their algebra. No matter how well they understand and can apply theorems, formulas or rules, they must have solid algebra. Algebra is the grammar and puntuation of Math. In English you can’t write a great essay with bad grammar and punctuation, regardless of how good the topic is. In Math, you can’t solve problems without good use of algebra. Some algebra takes time and experience to develop. However, there are common algebra mistakes that I see many times every day. You can avoid making these now and never waste those marks again. Any questions about this video drop us a message HERE.
