Collecting like terms means to simplify terms in expressions in which the variables are the same. In the expression \(5a + 2b + 3a - 6b\), the terms \(5a\) and \(+ 3a\) are like terms, as are \(2b\) ...

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 purpose of all of the developmental mathematics courses is to support student success academically and beyond by advancing critical thinking and reasoning skills. Specifically in Algebra II, as a ...

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 ...
