How do you set the calculator to keep track of the number of entries and give a total?

On the top right there is a slide button ...move the button to "item". this counts the quantity of items you enter. hit the * to get the total and the count.

This calculator does not have a key that you can use to find the prime factor of an integer.

You can however use the calculator to find the factors

1.** If number is even divide it by 2**

Keep dividing by 2, while keeping track of how many times you divided by 2.

If you divided 5 times by 2 before getting an odd number, then your first factor is 2^5

2.**Now try dividing by 3**, keep track of the number of times you divided by 3 before you could not divide by 3 any more. If you divided 0 times by 3, your second factor is 3^0, or 1 and 3 is not a factor.

If you divided 4 times by 3, your second factor is 3^4

3.**Divide by 5,** until you can't any more. Keep track of the number of times you divided by 5.

4. Divide by all other prime numbers 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, etc. For each prime number, keep track of how many times you divided by it, until you could not any more.

**Example: 23100**

*Division by 2*

23100/2=11550 ---------> 1 division by 2

11550/2=5775 ----------> 2 divisions by 2

Note that 5775 is not divisible by 2.** No more divisions by 2. **

First factor is 2^2

*Division by 3:*

5775/3=1925 ----------> 1 division by 3

1925/3=641. 66667 Not an integer. No more divisions by 3.

**2nd factor is 3^1**

*Division by 5 (number ends in 5)*

1925/5 =385 -------> 1 division by 5

385/5=77 ----------> 2 divisions by 5 and no more (quotient does not end in 0 or 5)

**3rd factor is 5^2**

*Division by 7 *

77/7=11 --------> 1 division by 7, and no more

**4th factor is 7^1=7**

*Division by 11*

11/11=1

**5th factor is 11^1=11**

Assembling the factors 2^2, 3^1, 5^2, 7, 11

Prime factorization of 23100 is

**23100=(2^2)(3)(5^2)(7)11**

You can however use the calculator to find the factors

1.

Keep dividing by 2, while keeping track of how many times you divided by 2.

If you divided 5 times by 2 before getting an odd number, then your first factor is 2^5

If you divided 4 times by 3, your second factor is 3^4

It doesn't have one. The calculator keeps track of whether you've hit a digit-entry key since you last pressed a function key. If you haven't, then the calculator computes the value and displays it. If you have hit a number-entry key, it stores the value. Thus, when the book says something like "press CPT then press PMT", you just need to press PMT.

Your Texas Instruments calculator has a built-in printer for producing a permanent record printout of

your calculations with negative numbers printed in red. A big, easy-to-read display also enables you to

check entries or perform quick calculations without printing.

GETTING STARTED

OFF ON PRT IC GT

POWER

1. Connect the calculator to a proper power outlet (110-120V or 220-240V

where available).

2. The calculator is turned on by setting the POWER switch to the PRT

position.

Inserting the paper (see illustrations 1, 2, 3, and 4 on page ii).

1. Turn on the calculator.

2. Open the printer compartment cover by pressing down on its front edge and sliding it back in the

direction of the arrow.

3. Fit the roll of paper on the holder so that it unrolls from the bottom, with the loose end toward the

calculator.

4. Cut the end of the paper squarely and insert it firmly into the printer slot on the back of the

calculator.

5. Press & until the paper is in the printing position.

Replacing the ink roller (see illustrations 5 and 6 on page ii)

1. Turn the calculator off and tear off the excess paper.

2. Remove the printer cover by pressing down on both sides of the front edge and sliding back in the

direction of the arrow.

3. Remove the old ink roller by lifting it with the removal tab.

4. Insert the new ink roller into the compartment and press down gently until it snaps into place. Close

the printer compartment.

Note: The old ink rollers should not be refilled. Replacement rollers can be obtained from your local

retailer. The warranty does not cover ink roller replacement.

The printer is on and an item count of additions and subtractions to or from

the register is printed when sub-totaled or totaled.

The GT position controls whether or not the totals from the independent add

register are accumulated in the grand total register.

ROUND Rounds the result of a calculation to the selected number of decimal places.

Truncates the result to the selected number of decimal places.

Rounds the result up or down according to its value. For example, when the

DECIMAL switch is set to 2, the result is rounded up if the third decimal

position is 5 or more and rounded down if it is 4 or less.

Rounds the result up to the selected number of decimal places.

The way to do math on this calculator is a bit different than on others. To start off, when doing subtraction, you must press the + key. This tells the calculator that you are working with a positive number.

Say you have $588.43 in you check book but you spent $136.92. The buttons you press on the calculator will be as follows:

588.43 + 136.92 -

The positive total of 451.51 will be on your screen. If you are using the print function as a way of keeping track, press # to print the on screen total.

Just remember, enter your first number and hit +. After this, each number that you are subtracting will have a - behind it.

Hi,
I guess you mean vacation accrual. It's hard to help you here, without knowing the exact accrual formula.
However here are some tips:
Set up a column with the start date for each employee and use the today() function to get today's date.
You can use the days360() funtion to calculate the number of days between two dates, assuming regular 30 days/month.
For more date related functions, click on the Fx (letter f with an subscript x) to the left of the value/formula entry field at the top of the spreadsheet. Thsi gives you a wizard with a list of functions. Select the Data/Time group and you see all available functions and can interactively pull them together.
Good luck
