Where is the percent % key? - Sharp el-531x scientific calculator

I haven't worked on that model but usually you want a percent plus key, not a percent minus. You either add in a percent plus key to the keyboard, or you change the sign to plus in the settings. Check your manual for any info it has on the percent plus function.

5/16 as a percentage is,
0.3125*100-
31.25%

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.

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

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

The keyboard of the typewriter differs from country to country to adjust to special characters used in its language.
In the standard US keyboard the percent sign is in number 5 key. To insert the percent symbol you would use right or left [SHIFT] + number 5 key , provided you are using the standard daisywheel,

Hi. It depends upon the model, but you may have a %+ key. If so, type 15 then press the percent key. if it takes 15 percent off (discount), then you will need to change the sign of the percent key to a surcharge.

Let me know if you need more help (model number please)
