An equality.
Equivalent expressions.
If both equations can be simplified to the same value, they are equal.
The same overall value.
You can have infinitely many mathematical expressions that equal 13. Or any other given number. For example, 13 + 0, 12 + 1, 11 + 2, etc., then 0 + 13, - 1 + 14, -2 + 15, etc. ... there you have infinitely many. You can make up lots of other types of expressions that give the same result.
2+2 = 2*2 = 2^2 all simplify to 4. But there is no special name for the three expressions.
When two expressions are equal to each other they form an equation.
An equation, or, perhaps an equality. 5X - 5 = 20 this equation has the same value that will satisfy it, with some manipulation this is two expressions having the same value 10 - 6 = 2 + 2
They are called: Identical equations or IdentitiesSee: http://www.tutorvista.com/search/value-algebraic-expressions-33 - -7 = ss = -26
Equivalent expressions.
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.
unequal
They are identities.
equivalent
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.
algebraic expressions
why should u care
They are equivalent fractions.
