What is the exponential form of 9.9.9.4.4?


for this I like to use logarithms to solve for N
reason 4 this is logarithms are the reverse of a exponential

log's have specific rules that exp's don't have to follow hence it makes it easier to solve for answers
using the formula logb(mn) = n ยท logb(m) will allow you to solve for N then just reverse the answer (do that in your head!!) and whhoollaaa! its an exponential !!!! neetooo

heres the log rules I was telling you about ! they apply to all log's uses

1) Multiplication inside the log can be turned into addition outside the log, and vice versa.

2) Division inside the log can be turned into subtraction outside the log, and vice versa.

3) An exponent on everything inside a log can be moved out front as a multiplier, and vice versa.

What is factoring and give the examples


Quick-Start Guide When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms. At this point the calculator will attempt to factor the expression by dividing a G C F, and identifying a difference between two squares, or factorable trinomials. Use the following rules to enter expressions into the calculator. Variables Any lowercase letter may be used as a variable. Exponents Exponents are supported on variables using the ^ (caret) symbol. For example, to express x 2, enter x ^ 2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses. Parentheses and Brackets Parentheses ( ) and brackets [ ] may be used to group terms as in a standard expression. Multiplication, Addition, and Subtraction For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is optional when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * ( x + 5 ) can also be entered as 2 ( x + 5 ) ; 2 x * ( 5 ) can be entered as 2 x ( 5 ). The * is also optional when multiplying parentheses, example: ( x + 1 ) ( x - 1 ). Order of Operations The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error. Division, Square Root, Radi cals, Fractions Division, square root, radi cals, and fractions are not supported at this time. A future release will add this functionality.

that's all I can say basically I learned it this way.

How to convert Fahrenheit to Celsius


Put 70 in for F, and apply BEDMAS, the order of operations, brackets, exponents, division and multiplication, and finally addition and subtraction. In this case, we have to do the brackets first before the multiplication and division. The answer should be 21 degrees Celsius.

What does poduct mean in maths


When you perform an arithmetic operation such as addition, subtraction, multiplication, or division the result has a specific name. The result of addition is called the sum; the result of a subtraction is called the difference; the result of multiplication is the PRODUCT. Finally the result of a division is the quotient.

Sample of how to create a python program that will input two numbers and will ask the user of operation to perform as to addition,subtraction,multiplication or division the program should perform the...


Assuming that the input numbers are given by the user:print "Menu"print "1. Addition"print "2. Subtraction"print "3. Multiplication"print "4. Division"print "0. Quit"
a = input("Please make a selection:")if a == 1: x = input("Please enter a number:") y = input("Please enter another number:") answer = x + yprint "%r plus %r = %r" % (x,y,answer)elif a == 2: x = input("Please enter a number:") y = input("Please enter another number:") answer = x - yprint "%r minus %r = %r" % (x,y,answer)
The same goes for everything else just with different signs. Don't forget that "*" is multiplication and "/" is division. Also, for 0. Just use:
elif a == 0: quit

I don't know what all the buttons mean ??????????????????


You cannot be serious. The digit keys allow you to enter the digits that make up the number you are using in your calculations. +, x, - / allow you to perform an addition, a multiplication, a subtraction, or a division. Keys with x^2, sin, tan, cos, log, allow you to calculate the relevant functions.
You get the idea.
To learn how to use the calculator, read the manual. At least skim through it looking for instructions on how to use a particular task. There is no shortcut.

Negative exponents? .825/(10^(-3)) ? Not sure how to get it to do the negative exponent.


You entered it correctly. Although you can leave out the parentheses if you want. The calculator will do exponents before it does multiplication or division just like it does multiplication and division before it does addition and subtraction. It has a built in order for hierarchy of operations. You only need to use parentheses if you want to do something that is different from this order. FYI, dividing by a negative exponent is the same as multiplying by a positive exponent. You could enter it in either way. .825/10^-3 = .825*10^3 = 825. I hope this helps you out.

How do I add and subtract on this thing?


Hello,
I do know what calculator you have but on most calculators you have digit keys to key in numbers, operation keys (multiplication, division, addition, subtraction), function keys (log, exponential, %, square root, square or a power) and you have the = key to obtain the result of the calculation.

Press the [ON] button

To add 2 numbers, exemple 12 and 13
12 [+ key] 13 [= key]. Calculator displays 25, or 25.00 or 25.0000...

To subtract
13 [- key] 7 [=key] . Calculator displays 6 or 6.00, 6.0000....

To multiply
32 [x key] 5 [= key]. Calculator displays 160.

You may have memory keys, to store values. They may be labeled M to enter a number in memory, M+ to add a number to the one already in memory, M- to subtract from the number already in memory.

Hope it gets you started.

Calculations in Adobe 8.0


Are you using live cycle (Part of Adobe 8)
On the RAW form - select from main bar - Window, Script Editor

Your Addition or Subtraction will be :
Field 1 + Field 2 or Filed 1 - Field 2
For division, change this to Field1 / Field2
For multiplication, Field1 * Field2

I have a PDF (Created in Livecycle that calculate standard deviation in tabular format) - currently working on the graphical representation
