When an expression is equated with some other parameter or value then it becomes an equation. for Example Principal * Time * Interest Rate /100 is an expression. Now when we equate this with Simple Interest and say
SI = Principal * Time * Interest Rate /100 then this is an equation.
Now in an equation like the one above, value of few parameters (SI, Principal, Time, Interest Rate all are parameters) will be known and value of some parameter will be unknown or may keep changing in any situation. These unknown or changing terms are called variables.

What Algebraic expressions?
An expression with a variable.
Do algebraic expressions have to have a variable?
Yes. That is the definition of an algebraic expression.
How do you solve algebraic expresions?
You solve algebraic expressions by getting the variable by itself.
What are expressions that contain the same variable?
an algebraic expression
What are numerical expressions that are equal or algebraic expressions that are equal for all values of the variable?
483h4yg3h45
Do algebraic expressions contain at least one variable?
yes.
How can you have different values in algebraic expressions?
When the value of a variable in an algebraic expression changes, the value of the expression can change.
Why are algebraic expressions called variables?
Algebraic expressions may contain variables but they are not normally called variables. In fact, if they are related to identities, they need not be variable. For example, (4x2 + 8xy + 4y2)/(x + y)2 is an algebraic expression, but it is not a variable: it equals 4.
What is a verbal expressions for the algebraic expression 7p?
Seven multiplied by the variable "p"
Two algebraic expressions are if they have the same value for all values of their variable?
They are identical or equivalent.
What is algebra expressions?
It is an expression of algebraic terms with no equality sign
What is the difference between a numerical expression and a algebraic expression?
Numerical expressions solely include numbers, while algebraic expressions may contain a variable like x. An example of a numerical expression is 1+2 and an example of an algebraic expression is 2x+3y=0.
