Whose fault is it if the calculator does not have a special key to implement such a trivial function.? If you are upset because of that, you should let TI know.
I was merely trying to show you that you can make do without that precious of functions. You can also buy a dirt cheap calculator from a dollar store and use it specifically for calculating percentages.

### I can't figure out how to use percent sign?

If I want 2/5 as a percentage (which is 40%), I would press
[2] [ /] [5] [%]

Of course this is a simple calculation. If you want advanced calculations let us know.

### How do u get % on it

On calculators you do not usually get percents. Instead, you get values which can be converted to a percent. For example what percent is 245 out of 987. You divide 245/987=.248. This is essentially the same as saying 24.8 percent. You move the decimal over 2 values. You can also round to get a nice percent number such as 25 percent.
If you are trying to put in a percent lets say you have to find 47% of 80. You just multiply .47 * 80= 38.4

### How do you make a percent sign

You can try to look in the Catalog of commands : Press [2nd][0] to open the (CATALOG) , but you will not find it. The symbol just does not exist. There is compound symbol in the Finance applications (TVM) it is called tvm_I% but you cannot isolate the percent sign from the other symbols.

Against my better judgment that whispered to me not to answer this question I had to tell you the truth, even if it gets you mad at me. Sorry.

### Acer,Aspire 5720-4663 Math calculator: How does one use the percentage function?

Hi. Try this steps on using your math calculator for the percentage function.

Hope This Helps

Step 1. Note that not all calculators behave the same way as far as the percentage key is concerned. Thus, test the examples in this article on your calculator. If your calculator does not have the percent key or does not behave in the way described here, don't despair - you can still use it to calculate percentages, it's just that you will have to press a few more buttons.
Step 2. Let's calculate a tip on your restaurant bill. Suppose your bill happens to be \$64.35 and you would like to leave 15% tip.
Type the following into your calculator: 64.35 * 15 %
Answer: 9.6525 or \$9.65 after rounding.
Most simple calculators will give an answer right here without having to press the = sign. If yours does not, press = and see if you get the right answer.
Alternatively, you can calculate this percentage by typing in
64.35 * 15 / 100 or 64.35 * 0.15
Thus, you may have observed that all that the percent key did here was division by a hundred.
Step 3. Let's calculate a grade percentage - say you got 34 out of a maximum of 40 points.
To figure out your grade percentage type in: 34 / 40 %
Alternatively, without the percent key: 34 / 40 * 100
Step 4. Let's calculate a sale price on those shoes that originally cost \$139, but are now discounted by 35%.
On your calculator type in: 139 - 35 % =
This calculation is amazingly easy with the percent key! Alternatively, you would first have to calculate what the 35% of the \$139 is and then subtract it from 139:
139 * 35 / 100 = 48.65
139 - 48.65 = 90.35

Hope This Helps

### How do I make a percent and delta sign?

Sorry, the TI83/83Plus/84/84PLUS/ Silver edition do not have a key or a command to calculate a %, or enter a % symbol. They do not have Greek alphabet letters either.
However in the Finance application there is a TVM variable called tvm_I% but you cannot isolate the % symbol. Similarly, in the TABLE setup you have DeltaTbl variable that fixes the step in a table, but you cannot isolate the Delta symbol.

These are the native capabilities of this family of calculators, and that does not mean that there does not exist a third-party program that can do what you want. You can look on the ticalc.org website.

Just wondering, why would you need these particular symbols when they mean nothing to the calculator?

### Calculating Percent savings

Since I don't use the percent sign. Here is instead a MUCH easier way. Divide the price you bought it for (289) by the original price (648). This gives you the percentage that 289 is with respect to 648 if you just read off the first two decimal places. When you divide one number by another it will tell you how many times they 'fit' for the purpose of explaining it. That is also essentially what a percentage is out of 100 parts. so when you divide one number by another, you will get a decimal answer, just multiply it by 100 (or just take the first two decimals) and that is percent saved (percent different). Note that if the first value is LARGER than the second, you will have a percentage of over 100%.
