Evaluation is the process of finding the numerical value of an expression. For instance, suppose you wanted to know what x^3 was when x = 2. You would plug in 2 for x and get 2^3. This process is evaluation.
Simplifying an expression on the other hand doesn't necessarily involve finding any particular value. For instance, suppose you started with the expression (x^3)/(x^2) then recognized that the numerator and denominator share a common factor of x^2 and so rewrote the expression as x. This is simplification because you've put the expression into an equivalent form that may be easier or more useful to deal with, but you have not found a specific value.
You can also simplify numerical values -- for instance, 12/20 can be rewritten as 3/5. Often it's necessary to simplify a numerical expression after evaluating an algebraic one.

What is the difference between research and evaluation?
The difference between research and evaluation is that research is were you find out about something and evaluation is were you say what you think of your work how you can improve it you usually evaluate your work once you Finnish something.
What is the difference between an expression and a numerical expression?
it has to have an x number in it.
What is the difference between a numerical expression and a variable expression?
A variable expression includes variables.
Difference between expression and equation?
An expression has no equal sign whereas an equation does have an equal sign
What is the difference between expression and equation?
The difference between these two is that an expression only contains variables, numbers, and mathematical symbols, and an equation contains two expression with an equal sign that separate them. For example, while an expression is "2x-1", an equation is "2x-1 = 5x."
What is difference between regular expression and regular definition in compiler?
Regular expression is built in and the regular definition has to build from regular expression........
What is the difference between conclusion and evaluation?
A conclusion explains what you found out by your research. An evaluation explains what went well and what could have been improved and how.
