For some reason, when you are working with 10^x powers the calculator assumes that that 1 = 1X10 so therefore if you want to use the ee button with a 10^x power you have to type it in as 1^x.

In short anytime you are working a problem in which you have to multiply something by 10^x you should type 1^x instead. Everything else should be typed normally. Then you will get the correct answer.

It should be 0.01 not 0.1 coz its the inverse.I f you rewrite it, it would be like this 1/10 to the power of 2. When the power is negative it would be dividing one.

hope I help

How do I use the % button on the casio MS-80b calculator- when I try to do a deduction or any calculation with the % button it gives the wrong answer

It seems you have to use the key procedure exactly to get the correct result.

From the Casio website,

Make sure that you are following the correct procedure.
Adding 10%: 200 [×] 10 [%] [+]
Subtract 10%: 200 [×] 10 [%] [-]

Good luck,

I have Casio Clacuator fx-991MS and it gives wrong answer like

The answer is correct. It is your understanding of priority of operations that is at fault.
As written your expression is calculated as follows
-2/2600 +10+3.
To ensure that an expression is calculated as you want it, enclose parts of it in parentheses. See the screen capture below.

Assuming you mean 10000 times 1.0075 raised to the power of negative 24, press

1 0 0 0 0 * 1 . 0 0 7 5 y^x 2 4 +/- =

The y^x key is just above the 9 key. The +/- key is just below the 3 key.

5000e to the (0.08)power time (2)

On this calculator the exponential function requires the argument be entered first. To calculate the exponential of a number, you enter the exponent (0.08) then press [2nd][LN].
For your calculation, you should calculate e^(0.08) then multiply the result by (5000x2=10000). The result should be 10 832.87068

We are not obtaining the correct answer when computing the I/Y. The problem is N=30, PV=-500, PMT = 0, FV = 10000. We are getting 126.01

Since you didn't specify what result you were expecting, I can only guess at what you want.

The answer is correct assuming 12 periods per year. To have 500 increase to 10000 in 30 months, you need an annual interest rate of 126%. For a more realistic result, set the number of periods per year to one by pressing 1 SHIFT [P/YR] then repeat the calculation. This will produce 10.5% for the annual interest rate.

Alternatively, if the interest is compounded monthly, specify 360 for N. This will give a value closer to 10% annually, compounded monthly.

Convert to scientific notation 45,700

45 700 = 45700.00..... Notice the decimal mark inserted after the second 0.
In scientific notation you must have ONE digit before the decimal mark: 4.7500 (it is not finished).
By moving the decimal mark from its original place after the second zero to its new place after the 4, you have divided the number by 10000 (one zero for each position change). To recover the original number you must multiply 4.57 by 10000. This is compacted as *10^4.
Thus 45700=4.57*10^4 or as the calculator displays it 4.57E04
If you are entering a number in scientific notation do not use *10^04, but press the [SHIFT][,] for a TI83Plus, followed by the exponent.

Hi. my calculator canon f 604 is acting wierd. when i press 10 EXP 2 , it gives me 1000 instead of 100. please help me out there is a problem in my calculator. for each exponent it gives one extra like...

You're getting the correct results. The "EXP" means "times ten to the". When you press 10 EXP 2, you're asking for 10 times ten to the second, which is 10 times 100 or 1000. If you just want ten to the second, press 1 EXP 2.

I have the 30xa and when i type in exponents and use the ee key it gives me th wrong value. for ex if I type in 10 EE 3 it gives me 10000 instead of 1000.

10EE3 is supposed to be 10000. 10EE3 is 10 times 10 to the third, which is 10 to the fourth. If you want 1 times 10 to the third, enter it as 1 EE 3, which will give you 1000.

I am trying to calculate a problem using scientific notation but it is not giving me the correct answer and my calculator is set to 9 dec places the equation is 1.9x10^10- x 453.6 / 163871 I keep getting...

Your notation expression contains an extra symbol ( either the - or the second x).
If I enter
(1.9x10^10)x453.6/163871 I get 5.262148845 x 10^7 about 5.3 x10^7
If I enter
(1.9x10^10 - 453.6)/163871 I get 1.159 x 10^5.
Your result is off by a factor of 100 to 10000.
As to the scientific display mode, you set it by pressing [MODE][->][SCI][ENTER] [2nd][QUIT]. You can leave the Float option to 9 digits if you want.

Hope it helps.

Honda radio code

either the radio code is wrong or you have locked the radio down you only have three attempts to enter the correct code if this is the case disconnect thenegative battery cable for 10 minutes then reconnect and try again. If the code is wrong the audio unit will have to be removed so you can get the serial number to give to the honda dealership so they can get the correct code
