Algebraic expressions contain alphabetic symbols as well as numbers. When an algebraic expression is simplified, an equivalent expression is found that is simpler than the original. This usually means that the simplified expression is smaller than the original.
There is no standard procedure for simplifying all algebraic expressions because there are so many different kinds of expressions, but they can be grouped into three types:
(a) those that can be simplified immediately without any preparation.
(b) those that require preparation before being simplified.
(c) those that cannot be simplified at all.

What do you call replacing a variable in an expression by a number and simplifying the result?
That is called 'solving'.
The rules for simplifying an algebraic or numerical expression?
There are a few rules for simplifying an algebraic expression. Specifically, one should combine like terms, and then they should try to isolate the variable by doing the opposite, either multiplication or division.
To find the value of an algebraic expression by substituting a number for each variable and simplifying?

What is the difference between simplifying and evaluating algebraic expressions?
Simplifying an expression is getting rid of any brackets or parentheses, performing as many operations as you can - including combining like terms. To evaluate an expression you would substitute the numerical values of all the variables, carry out all the operations (addition, multiplication etc) in the expression to reach the answer - the numerical value of the expression.
What does simplify the expression mean in math?
Basically, simplifying can apply to any sort of expression from something as simple as division, or something complicated like an equation. Simplifying can be like reducing 5/10 to 1/2 or reducing 10x+5y+25 to 2x+y+5. You divide the expression by a common term, such as two or five in the previous problems
