Question about Casio DF320TM Scientific Calculator

Ad

You are actually telling the calc to do 100-10 then convert it to percent. so 100-10 is 90 and what percent is this would be 9000%, but if you actually mean 900% then you have to have a switch turned on that makes it advance the decimal place on the 100 and not the 10%. i would read the users manual in detail, not just about the % but everything or maybe start changing the swtiches and see where you end up.

Calculators have two similar signs: the regular minus sign for subtraction, and the negation (change sign) sign. When applied, the latter changes the sign of the quantity to which it is applied. The minus sign - for subtraction is on the central line, the negation sign is smaller and somewhat raised above the center line.

The change sign key may be marked**(-)** , **(+/-)**, or **+/-**

Minus and change-sign are two completely different things. Minus is used to subtract one number from another. When you press minus when the input line is empty, your telling the calculator to subtract. The only way it can subtract the number you're about to put in is to subtract it from something else, and that something else is the previous answer, hence the "Ans."

If you want to input a negative number, use the change-sign key. If you want to subtract one number from another number, use the minus key.

Try pressing the plus key when the input line is empty. You'll get Ans+ in this case as well, The same with multiply and divide, among others, and for the same reason.

Hi,

You can use either of this 2 equations.

ex: 75% off of 20

Equation 1: 20 minus (-) 75% = 5

Equation 2: (20*0.75) = 15 then press Ans key

20 - Ans = 5

Hope this helps.

Your function as written will always return -1. You need to make the calculation to convert cups to milliliters:

double convertCupsToMilliliter(double cups) {return cups * 236.518538;}

double convertCupsToMilliliter(double cups) {return cups * 236.518538;}

Hello,

The calculator has two minus signs

Examples. Let (-) be the negation and -- the regular minus.

You can enter it exactly as it is written above. In this case, you must use the change sign (-) in both factors.

You can also decide to use the power rules and enter the expression as X^( -2 --1/3). In this case the first minus is the negation and the second is the regular minus.

I could go on with a few more examples, but that will take us away from your present concern.

In short.

Do not forget to rate the solution

The calculator has two minus signs

- The regular MINUS sign which is used with the subtraction operation. This operation is binary, requiring two operands (two terms). In a-b, a and be are the operands (they very specific names, but I will skip this detail).
- The negation or change sign. This operation is called unary, requiring one operand. -a means take the negative of the number a.

Examples. Let (-) be the negation and -- the regular minus.

- If you enter (-) 12 the TI84Plus accepts it and calculates the negative of 12.
- If you enter 12 (-) 13 the TI protests with a syntax error
- If you enter 12 ( (-) 13) the calculator interprets it as 12* (-13) and calculates -156.
- If you enter --12, the calculator displays Ans--12, where Ans is the last result calculated. If Ans happens to be 0, the new result is obviously the one you are expecting. But if Ans holds a non zero value, this is incorrect.

You can enter it exactly as it is written above. In this case, you must use the change sign (-) in both factors.

You can also decide to use the power rules and enter the expression as X^( -2 --1/3). In this case the first minus is the negation and the second is the regular minus.

I could go on with a few more examples, but that will take us away from your present concern.

In short.

- If the minus sign is the leftmost (first) symbol in your function (after the Y1=) you should use the negation. Any subsequent minus should be the regular minus --
- If the minus sign is the first symbol in an exponent, you must use the negation. Any subsequent minus in the expression of an exponent should be the regular minus --

Hello,

Calculators usually have two minuses, the regular minus sign and the change sign sometimes labeled (-) or (+/-). The latter is not meant to effect a subtraction, but to take the negative of the number you just entered. Big difference, would you say, but the syntax is different.

Ex: 15 - 7 is a subtraction with result 8

10 (-) displays -10 on the screen.

In some calculators the change sign is smaller than the regular minus, and is raised above the main line.

Hope it helps.

try changing the back up battery also. This generally helps. The next time you change your batteries, change them one at a time. don't take them all out at once. This won't happen if you do it like that.
