It is impossible to learn algebra in one day, but you can familiarize yourself with the basic concepts that build to everything else. Algebraic equations and inequalities are solved by isolating variables. Algebra also works with integers, or positive and negative numbers. Adding a negative number is the same as subtracting a positive number, and vice versa. When multiplying or dividing integers of opposite signs, the result is negative; when they are the same sign, the result is positive.

When solving equations, follow the order of operations and do the same operation to both sides of the equation to keep it balanced. When possible, perform the expressions in parentheses, then exponents, then multiply or divide, and finally add or subtract.
Finally, when working with equations, you can only add or subtract like terms. These are terms that have the same variable and exponent, such as 3x and 6x; you can combine them because you know x has the same value.
