Working with multi-variable expressions is a key concept in algebra that involves manipulating expressions containing two or more variables. This video offers a detailed guide on understanding and ...

To expand a bracket means to multiply each term in the bracket by the expression outside the bracket. For example, in the expression \(3(m + 7)\), multiply both \(m\) and 7 by 3, so: \(3(m + 7) = 3 ...

Algebraic expressions can be expanded - multiplied by one or more terms. They may also be simplified – made shorter and simpler by collecting like terms. Multiply \(-3\) by \(-4\) using the rule for ...

The vast majority of students won’t take algebra until middle or high school. But teachers can start laying the groundwork for this pivotal class a lot sooner, some researchers say—and instilling ...

Google has added a bunch of examples to the potentialAction.mathExpression-input section of the Math Solver help documentation. These examples explain how to handle derivatives, integrals, and limits ...
