How would you write 2(x+4) as a verbal expression?

Answer 1

I would express it verbally as "number #2# times the sum of an unknown #x# and number #4#. Alternatively, you can say "double the sum of an unknown #x# and number #4#".

In general, it is better to describe the algebraic expressions using mathematical symbols rather than just shorter text because it enhances reader comprehension.

The process that typically takes place is the reverse: a problem is stated orally, and in order to solve it, a student usually converts it into an algebraic expression. This is a useful comprehension exercise that also enables a teacher to assess a student's speed at understanding the material.

An accurately represented verbally stated problem in algebra is typically a reliable predictor of a correctly solved problem.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
