It's the key marked "I/Y" (for interest per year), located second from the left on the third row from the top.

To use the power, you use the y to the x key, above the EXP key. To enter 2 to the power of 4, you enter 2 hit the y to the x key and enter 4 and hit enter.

To use percent function, you enter the percent key after the number. To calculate Interest, where Interest = Principal x Interest x Time. For example, if the principal is $1,000, the interest rate is 8%, and time/term is 4 years, we would enter 1000 x 8 Percent x 4. When the8 is entered followed by the percent key, it should turn into 0.08.

Good luck,

Not all calculators have a percentage key. I think of percent as per cent, or per 100. You can always multiply by 100 to get the percentage.

For example, 0.23 as a percent would be 0.23 x 100 or 23%.

Good luck.

It is the number " 1 " key. You have to depress a different key first. I think that it is the " 2ndF " key. The % is just above the number " 1 " key. All or most of the keys perform a dual function or purpose.

Sad as it may be, this calculator does not have a % button/key/menu. So do not look for it. However you can still convert your decimal numbers to percent values.

1 %= 1 per cent (100) = 1/100=0.01

0.01=0.01*100/100=(0.01*100)/100=1/100=1%

To convert a decimal number to %, move the decimal mark two places to the right.

To convert a percent value to a decimal value, move the decimal mark two places to the left and drop the % symbol.

75%=0.75

135%=1.35

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

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 %

Answer: 85

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 % =

Answer: 90.35 or $90.35

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

Have you tried messing around with the decimal setting and setting if to F (floating) or somethings besides 2? This should affect your inputting of numbers however. You're not hitting the percent key (%) by any chance, are you. I don't have this calculator but I'm not aware of any function that inserts a decimal point in a number that you enter (other than the percent key). The decimal setting should only affect the number of decimal points in the answer. Good luck and let us know how you make out. I'm curious.
