An expression is a combination of numbers, operators, grouping symbols (such as brackets and parentheses) and/or free variables and bound variables arranged in a meaningful way which can be evaluated. Bound variables are assigned values within the expression (they are for internal use) while free variables can take on values from outside the expression.

This tutorial will show you how to solve linear equations with multiple steps. In order to solve for y, you need to combine like terms. First, reduce by adding constants on the left hand side together, then next, you should combine like terms, y's, and then get y by itself with undoing mutliplication using division.

By showing me correct steps and procedures to solve algebraic expressions,etc.

Hopefully simplifiying expressions so I can move on in algebra.

Help me understand algebraic expressions better.

I hope to get a better understanding on how to factor out expressions.

Understand evaluating expressions with decimals more better.

To learn how to work word problems, algebraic expressions with variables, rates,y=mx+b or y=mx-b, and knowing what these variables stand for on a graph, fractions conversions etc.

I hope your site will help me to understant radical expressions.
