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

By harnessing randomness, a new algorithm achieves a fundamentally novel — and faster — way of performing one of the most basic computations in math and computer science.

We describe learning situations that were the subject of the empirical study, which involved forty students in two 8th-grade classes. The aim was to teach the formal solving method, which involved ...

For instance, being able to solve multi-step linear inequalities requires students to first know how to write and graph inequalities—a 6th grade skill—and translate algebraic inequalities from ...
