forms a complete algebraic thought; has a verb; e.g., an equal sign
"expressions" are like phrases, and "statements" are like sentences
We use algebra to solve for an unknown, that is, when we have incomplete information and we're trying to find out the missing parts; therfore, in order to address, to speak about, the problem, we arrange what we know and don't know as single-item "words" (terms) and "phrases" (expressions) and "sentences" (statements) with which we might structure the issue, or begin to formulate the data into a complete thought of problem solving.
