SAT Prep: Test 7 Section 5 Part 3
Choosing the "quick and dirty" method of solving problems rather than more mathematically complicated, Sal shows students the importance of time management when taking the SAT (or other math tests). He still arrives at correct answers,...
Curated OER
What are Like Terms?
Combine those like terms! What does that mean? How do I do that? Find terms with the same variable and find terms with the same powers and combine their coefficients.

How Do You Add Polynomials Vertically?
The instructor demonstrates how to line up two polynomials vertically to add them together. She emphasizes lining up the terms with the same powers. She also identifies some places where there is no term and shows how to write a...
