Using Inverse Operations

Young mathematicians so often have a love-hate relationship with matrices and their inverses. They love the idea of a quick algorithmic way to solve systems of equations, but get stuck in the arithmetic precision required by the method....

In this inverse operations worksheet, students solve equations using inverse operations. A detailed example and explanation is available prior to the exercises. This two-page worksheet contains four problems.

It's time for them to show you what they've learned! The review provides a sampling of the different concepts learned throughout the eight-part series. Learners solve equations by combining like terms, applying the distributive property,...

Introducing inverse functions! The 20th installment of a 35-part lesson encourages scholars to learn the definition of inverse functions and how to find them. The lesson considers all types of functions, not just exponential and...

Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...
