How to create a formula for increase decrease percent in excel

If you have a number in Cell A2 (say 100), and you put the amount of percentage increase or decrease in Cell A3 (say -10%), then put this formula into Cell A4 to calculate the answer:
=A2*(1+A3) , which then shows as the answer (90).

Correct a #N/A error blueup_clv.gifShow All bluedrop_clv.gifHide All This error occurs when a value is not available to a function or formula.
  1. Optionally, click the cell that displays the error, click the button that appears ooui1_za06043871.gif, and then click Show Calculation Steps if it appears.
  2. Review the following possible causes and solutions. blueup_clv.gifMissing data, and #N/A or NA() has been entered in its place
    Replace #N/A with new data.
    Note You can enter #N/A in those cells where data is not yet available. Formulas that refer to those cells will then return #N/A instead of attempting to calculate a value.
    blueup_clv.gifGiving an inappropriate value for the lookup_value argument in the HLOOKUP, LOOKUP, MATCH, or VLOOKUP worksheet function
    Make sure that the lookup_value argument (argument: The values that a function uses to perform operations or calculations. The type of argument a function uses is specific to the function. Common arguments that are used within functions include numbers, text, cell references, and names.) is the correct type of value — for example, a value or a cell reference, but not a range reference. blueup_clv.gifUsing the VLOOKUP, HLOOKUP, or MATCH worksheet function to locate a value in an unsorted table
    By default, functions that look up information in tables must be sorted in ascending order. However, the VLOOKUP and HLOOKUP worksheet functions contain a range_lookup argument (argument: The values that a function uses to perform operations or calculations. The type of argument a function uses is specific to the function. Common arguments that are used within functions include numbers, text, cell references, and names.) that instructs the function to find an exact match even if the table is not sorted. To find an exact match, set the range_lookup argument to FALSE. The MATCH worksheet function contains a match_type argument that specifies the order the list must be sorted in to find a match. If the function cannot find a match, try changing the match_type argument. To find an exact match, set the match_type argument to 0.
    blueup_clv.gifUsing an argument in an array formula that is not the same number of rows or columns as the range that contains the array formula
    If the array formula (array formula: A formula that performs multiple calculations on one or more sets of values, and then returns either a single result or multiple results. Array formulas are enclosed between braces { } and are entered by pressing CTRL+SHIFT+ENTER.) has been entered into multiple cells, make sure that the ranges referenced by the formula have the same number of rows and columns, or enter the array formula into fewer cells. For example, if the array formula has been entered into a range 15 rows high (C1:C15) and the formula refers to a range 10 rows high (A1:A10), the range C11:C15 will display #N/A. To correct this error, enter the formula into a smaller range (for example, C1:C10), or change the range to which the formula refers to the same number of rows (for example, A1:A15).
    blueup_clv.gifOmitting one or more required arguments from a built-in or custom worksheet function
    Enter all arguments (argument: The values that a function uses to perform operations or calculations. The type of argument a function uses is specific to the function. Common arguments that are used within functions include numbers, text, cell references, and names.) in the function.
    blueup_clv.gifUsing a custom worksheet function that is not available
    Make sure that the workbook that contains the worksheet function is open and the function is working properly.
    blueup_clv.gifRunning a macro that enters a function that returns #N/A
    Make sure that the arguments (argument: The values that a function uses to perform operations or calculations. The type of argument a function uses is specific to the function. Common arguments that are used within functions include numbers, text, cell references, and names.) in the function are correct and in the correct position.

The Casio FX-300MS does not provide base 2 logarithms as a single key operation. However, you can use the natural logarithm (ln, base e = 2.7182818...) and the formula

log2 ( x ) = ln( x ) / ln( 2 )

To calculate the base 2 logarithm of 16, key in
[ln] 16 [/] [ln] 2 [=]
and get displayed the correct answer 4.

The same simple formula also works for any other base, and actually for any other logarithms provided by your calculator. The FX-300MS also provides a logarithm to base 10 (lg). You could also
[lg] 16 [/] [lg] 2 [=] to get the solution to the problem above, or
[lg] 25 [/] [lg] 5 [=] to get the base 5 logarithm of 25.

Electricity bill coding in java

First think how you would solve this problem yourself on a piece of paper. Then try programming it using the things you learned (if they've given you this assignment without teaching you to multiply, subtract and use if's, drop the course).
Well here is an idea.

Take the total kilowattage and send it to a function. What the function will do is subtract 14KW from the total Kilowattage and add the amount for the first 14KW then subtract 85KW from the total KW and add the amount for the 85KW. But once you subtract the number of KW from the total make sure to check if the total KW isn't negative, if so just break out of the function and return the total due.

Or if you have formula for how much the rate grows over how many miles.

For example lets say the rate grows by $1 every time the KW doubles you could have something like

int rate = 1; //Begining rate
int KW = 14; //First flat rate
int amount; //total amount they have to pay
while(totalKW > 0)
totalKW -= KW; //subtract the first rate
if(totalKW <= 0) //check if too much subtracted
break; //if so break
amount += rate; //add the rate to the total

rate += 1; // Add $1 to the rate every time
KW *= 2; // KW is doubled

Excel formula

the formulae for the surface area of round disc is
pi * r * r
where pi=3.14 and r =radious of disc= diametre/2 

for this 1st u have 2 calculate the radious of the disc that is
then convert it to  m by dividing 1000 ,so radious=90/1000=0.09 m
finally calculate the area= 3.14 * 0.09 * 0.09=0.025434 sq metres
for 38 disc multiply 38 with the above area that is
0.025434 * 38=0.966492 sq metres

in excel 2007  u can do it more easily by going 2 formulas tab.
Under formla tab click on engineering formula and  then convert
here u can convert from mm to m
after converting use the above formula i just told u.

Excel argument

If I understand correctly, you want to figure the normal wages at 40 hours and less. If there is more then 40 hours, calculate the normal 40 hours, then calculate the hours overtime (time and a half) and add them to get a total.


B5 columns are filled with this:

NOTE: The $ sign doesn't refer to money, it refers to an absolute reference so when copying a formula, the cell references with a $ sign are fixed and don't adjust according to the relative position to where it's being pasted.

Please rate as FixYa! or ask please clarify. ThankYa!
