This site offers numbers tricks to help multiply and divide large numbers mentally. There are also tricks for powers and roots of numbers.

Given the formula of a square-root or a cube-root function, find the appropriate graph. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Students solve quadratic equations by factoring and finding square roots, as well as by graphing.

This lesson will go over how to evaluate numerical with parentheses, exponents, square roots and/or absolute values.

This lesson will provide examples simplifying radical expression by applying the properties of square roots and prime factorization. It is 5 of 8 in the series titled "Simplifying Radical Expressions."

Is it any wonder that students are suspicious? We lead, sometimes drag, them through Algebra I insisting they must follow the order of operations. We make them learn the "hard way" of doing an assignment one day only to show them the...

Simplifying radicals that do not contain perfect squares can be done easily by following the steps outlined on this resource. Use the examples to see exactly how to do this.

This section explores the process for solving radical equations, including those with square, third, and fourth roots. It also investigates how, when, and why some solutions that appear to be correct are incorrect, and are therefore...
