Evaluating expressions with multiple variables: fractions & decimals Combining like terms with negative coefficients & distribution

To use a variable, we must both declare it—to let the program know about the variable—and then assign it—to let the program know what value we are storing in the variable.

Variables in math are symbols, often letters, that represent different values in various situations. They help us understand and solve problems with changing values.

Well, let me just do the division and convert to a decimal, which is very easy to convert to a percentage. So let's try to actually do this division right over here.

To apply the distributive property to an algebraic expression, you multiply each term inside the parentheses by the number or variable outside the parentheses. For example, to simplify 2 (x …

To solve an equation we find the value of the variable that makes the equation true. For more complicated, fancier equations, this process can take several steps.

Learn how to solve the equation 2x + 3 = 5x - 2 with the variable on both sides. We start by visualizing the equation, then isolate the variable by performing the same operations on both …

This topic covers: - Solving one-variable linear equations - Solving one-variable linear inequalities

Learn to write expressions with variables in math! Discover how to represent various operations like addition, subtraction, multiplication, and division using variables.

Simplifying radical expressions that involve variables. So let's say I have two times the square root of seven x times three times the square root of 14 x squared.
