Algebraic fractions are simply fractions with algebraic expressions either on the top, bottom or both. We treat them in the same way as we would numerical fractions. In part 1 we saw how to simplify, and add and subtract algebraic fractions. We discovered that algebraic fractions follow the same pri

A fraction consists of a numerator and a denominator, you can expand and cancel it. Adding and subtracting only works when the denominators are equal. Top calculator for school/university: http://amzn.to/2bkTSSC Top calculator online: http://www.wolframalpha.com/ Fraction basics, adding fractions,

Dividing a polynomial by an integer or an expression is really just another way of simplifying. There isn’t actually anything new to learn: you just need to be able to simplify numbers (like 20/15 simplifies down to 4/3) and know how to divide with indices (when you divide with indices, you subtra
