What does it mean to evaluate the exponential expressions?
It means to find the numerical value of the expression.
What are expressions that have the same value?
Equivalent expressions.
Which of these expressions always represents a negative value Which of these expressions always represents a positive value?
None of "these" expressions represent anything!
What is a function whose rule contains absolute value expressions?
An absolute-value function
Which expression has the value 0?
There are many expressions that have this value. The simplest one is the number zero itself.
What are expressions that have the same value no matter what x represents called?
algebraic expressions

Can numerical expressions have the same value?
Yes, numerical expressions can have the same value. For example, the expressions 2+3 and 5 both have the value of 5. Similarly, the expressions 2x3 and 6 both have the value of 6. In general, any two numerical expressions that evaluate to the same number will have the same value.
Identical in value?
Yes, some expressions can be identical in value.
When two expressions are equal in value?
They are callled: Identical equations or Identities See: http://www.tutorvista.com/search/value-algebraic-expressions
When two expressions have the same value they are?
equivalent
What expressions that have the same value are called?
They are identities.
Does an algebraic expressions have a single value?
Not necessarily.
When two expressions do not have the same value they are what?
unequal
What are the steps for rewriting expressions?
There are a few steps to rewriting expressions. The steps of rewriting expressions are finding the value of the letter and then using the common factor.
