Learn how to use inverse operations to find the value of an unknown variable in an equation, so that the value is true.

We propose a two-step estimating procedure for generalized additive partially linear models with clustered data using estimating equations. Our proposed method applies to the case that the number of ...

The use of concrete models for teaching students how to solve equations is often debated in scientific literature. This article aims to examine the balance model and to identify the issues that divide ...

But what if you could use your smartphone to solve equations by pointing the camera at the problem in your textbook instead of using a graphing calculator? That is the idea behind PhotoMath.
