Is Simplify The Same As Solve In Math
The difference between them is an extension of the difference betweenexpressions and equations. Simplifying can be done with either expressions or equations. Simplifyinginvolves making the math sentence shorter. Solving involves finding the value or values that makes the equation, or math sentence, true.

What Does It Mean To Evaluate In Writing
Evaluation is the process of examining a subject and rating it based on its important features. We determine how much or how little we value something, arriving at our judgment on the basis of criteria that we can define. We evaluate when we write primarily because it is almost impossible to avoid doing so.

Evaluating And Solving Functions
 Evaluate and solve functions in algebraic form.
 Evaluate functions given tabular or graphical data.
When we have a function in formula form, it is usually a simple matter to evaluate the function. For example, the function f\left=5 – 3^ can be evaluated by squaring the input value, multiplying by 3, and then subtracting the product from 5.
What Is Evaluation Plan
An evaluation plan is a written document that describes how you will monitor and evaluate your program, as well as how you intend to use evaluation results for program improvement and decision making. The evaluation plan clarifies how you will describe the What, the How, and the Why It Matters for your program.

What Does ‘evaluating Expressions’ Mean In Math
Evaluating any expression is a very simple mathematical concept. When you substitute a specific value for each variable, you perform an operation called evaluating an expression. A mathematical expression is algebraic, it contains a finite set of variables and numbers, and then algebraic operations. Evaluation makes printing easy.

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function.

Express the relationship 2n+6p=12 as a function p=f\left, if possible.
To express the relationship in this form, we need to be able to write the relationship where p is a function of n, which means writing it as p= expression involving n.
\begin& 2n+6p=12\\ & 6p=12 – 2n & & \text2n\text. \\ & p=\frac & & \text. \\ & p=\frac\frac \\ & p=2\fracn \end
Therefore, p as a function of n is written as

To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.
What Is An Example Of Evaluating A Polynomial

Evaluate x4 + 3x3x2 + 6 for x = 3.
This is my first polynomial to evaluate, so I’ll start again with empty parentheses, showing me where the variable’s value needs to be placed.
x4 + 3x3x2 + 6
4 + 33 2 + 6
81 + 3 + 6
81 81 9 + 6

Evaluate 3x2 12x + 4 for x = 2.
I’m glad I’ve practiced using parentheses to make my substitutions clear. In this case, those parentheses will help me keep track of the “minus” signs.
32 12 + 4
3 + 24 + 4

Evaluate y = 4x 3 at x = 1.
This is different. They’ve given me an equation with two variables, but have given me a value for only one of the variables. I guess they want me to plug in for x and figure out the resulting value for y.
y = 4 3
Then my answer is the equation:
y = 7
Note: In this last exercise above, we were plugging a value in for one of the variables, and simplifying to find the value of the other variable. Also, the part we were plugging in to had been set equal to a name, y. Because of this, we weren’t just evaluating an expression we were in fact evaluating a polynomial function. The result of our plugnchug means that the point = is on the line y = 4x 3 that is, this point is on the graph of the polynomial function.

Evaluating A Function Given In Tabular Form
As we saw above, we can represent functions in tables. Conversely, we can use information in tables to write functions, and we can evaluate functions using the tables. For example, how well do our pets recall the fond memories we share with them? There is an urban legend that a goldfish has a memory of 3 seconds, but this is just a myth. Goldfish can remember up to 3 months, while the beta fish has a memory of up to 5 months. And while a puppys memory span is no longer than 30 seconds, the adult dog can remember for 5 minutes. This is meager compared to a cat, whose memory span lasts for 16 hours.
The function that relates the type of pet to the duration of its memory span is more easily visualized with the use of a table. See the table below.
Pet  

Beta fish  3600 
At times, evaluating a function in table form may be more useful than using equations. Here let us call the function P.
The domain of the function is the type of pet and the range is a real number representing the number of hours the pets memory span lasts. We can evaluate the function P at the input value of goldfish. We would write P\left=2160. Notice that, to evaluate the function in table form, we identify the input value and the corresponding output value from the pertinent row of the table. The tabular form for function P seems ideally suited to this function, more so than writing it in paragraph or function form.
What Is An Example Of Evaluation

Evaluate a2b for a = 2, b = 3, c = 4, and d = 4.
To find my answer, I just plug in the given values, being careful to use parentheses, particularly around the “minus” signs. Especially when I’m just starting out, drawing the parentheses first may be helpful:

Note how using parentheses helped me keep track of the “minus” sign on the value of a. This was important, because I might otherwise have squared only the 2, ending up with 4, which would have been wrong.
By the way, it turned out that we didn’t need the values for the variables c and d. When you’re given a big set of expressions to evaluate, you should expect that there will often be one or another of the variables that won’t be included in any particular exercise in the set.

Evaluate acd for a = 2, b = 3, c = 4, and d = 4.
In this exercise, they’ve given me extra information. There is no b in the expression they want me to evaluate, so I can ignore this value in my working:

Evaluate 2 for a = 2, b = 3, c = 4, and d = 4.
I must take care not to try to “distribute” the exponent through the parentheses. Exponents do NOT distribute over addition! I should never try to say that 2 is the same as b2 + d2. They are NOT the same thing! I must evaluate the expression as it stands:
+ )2

Evaluate b2 + d2 for a = 2, b = 3, c = 4, and d = 4.
In this expression, the squaring is on each of the variables individually.

Evaluating Functions Expressed In Formulas
Some functions are defined by mathematical rules or procedures expressed in equation form. If it is possible to express the function output with a formula involving the input quantity, then we can define a function in algebraic form. For example, the equation 2n+6p=12 expresses a functional relationship between n and p. We can rewrite it to decide if p is a function of n.

Translate Words To Algebraic Expressions
In the previous section, we listed many operation symbols that are used in algebra, and then we translated expressions and equations into word phrases and sentences. Now weâll reverse the process and translate word phrases into algebraic expressions. The symbols and variables weâve talked about will help us do that. They are summarized in Table 2.7.

Look closely at these phrases using the four operations:
Each phrase tells you to operate on two numbers. Look for the words of and and to find the numbers.

Plug in ???8??? for ???x??? and ???3??? for ???y??? to the given equation.
???83=z???

Lets try another example of evaluating expressions.
Evaluating expressions means that youll be replacing or plugging in numbers for variables and then simplifying using the order of operations until you arrive at a single number.
Example
Use the given values to evaluate the expression, when ???a=2???, ???b=1???, and ???c=3???.
???abc+c^3+ab???
Plug in ???2??? for ???a???, ???1??? for ???b???, and ???3??? for ???c???. Remember that ???abc??? means ???a\cdot b\cdot c??? and so well need to use parentheses when plugging in these values.
???+^3+???
Now simplify using the order of operations. Exponents first since none of our parentheses are grouping symbols and instead mean multiplication.
