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.
A variable expression includes variables.
An equation has an equal = sign whereas an expression does not.
Regular expression is built in and the regular definition has to build from regular expression........
algebric uses variables and numerical uses numbers
a report is stating the facts plain and simple, whereas an evaluation is an analysis possibly with an opinion of the situation. An evaluation may also contain answers of how to improve the thing.
What is the difference between formative and summative evaluation?
what is difference between auditing, monitoring, controlling and evaluation
When you simplify, you are just taking the equation down to it's simplest form, not solving it. Evaluation involves actually solving the problem.
What is the difference between evaluating an expression?
Comparison happens after evaluation. Without evaluation ther is no comparison
Expression has no answer. a equation has an answer
Play Tekken and find out.
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.
it has to have an x number in it.
The variable.
A variable expression includes variables.
An equation has an equal = sign whereas an expression does not.
