What else can I help you with?
What are expressions that have the same value no matter what x represents called?
algebraic expressions
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!
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
In C plus plus all false relational expressions have a mathematical value of?
In C++ all false relational expressions have a mathematical value of 0.
Do expressions have the same value?
No, expressions cannot have the same value in algebra. They may be assigned to different values and on solving we can get different answers in each case.
