Two linear expressions can be expanded, and then simplified by collecting like terms, if there are any. Linear expressions have no terms with power of 2 or higher. For example, 15x – 4y is a linear ...

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 ...

Integer linear programming can help find the answer to a variety of real-world problems. Now researchers have found a much faster way to do it. Inspired by the results of a game-playing neural network ...

Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...
