Practice online or make a printable study sheet. Algebra skills build on one another, so make sure that you really understand each concept! (The symbols for numbers, after all, are nothing but written marks. Walk through homework problems step-by-step from beginning to end. Factoring can be used to simplify algebraic expressions to make solving simpler. **Algebraic answers.** And so are letters As the student will see, algebra depends only on the patterns that the symbols make.

That said, let us begin. Algebra is telling us how to do any problem that looks like that. And like any skill -- driving a car, baking cookies, playing the guitar -- it requires practice. You're doing a great job!

The rule means: Whatever those numbers are, add the numerators and write their sum over the common denominator. ) If your answers do not match the answer key below, watch the videos above for step by step solutions.

A LGEBRA IS A METHOD OF WRITTEN CALCULATIONS that help us reason about numbers. At the very outset, the student should realize that algebra is a skill. Hints help you try the next step on your own. The letters a and b mean: The numbers that are in the numerators.

Factoring is a useful skill to learn for the purpose of solving basic algebra problems the ability to competently factor becomes almost essential when dealing with quadratic equations and other forms of polynomials. Factoring can even give you the ability to eliminate certain possible answers much more quickly than you would be able to by solving manually. That is one reason why we use letters. Remember.

Written practice. An algebraic expression is an expression that contains one or more numbers, one or more variables, and one or more arithmetic operations. The letter c means: The number in the denominator. .
