Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
goodluck!

SOURCE: scientific notation

you want to hit mode not menu and then make sure that normal is flashing instead of SCI and hit enter. so just hit mode then enter and it should be normal

Hello,

1. To convert a number to scientific equation, use [2nd][Sci]
Exemples 12345 [=] screen shows 12345 Then [2nd][Sci] coverts it to 1.2345 ^04 to the power 4.
2. To enter directly a number in scientific notation (e.g. -1.2345 X10^(-65) a very small number) you use the [EE] key 1.2345[+ /-][EE][+/-]65 shows as -1.2345 -65
1.6X10^(-19) 1.6[EE][+/-]19 shows as 1.6 -19

Hope it helps

### How do i put powers on my calculator? Like 10 to the twenty third power...

Look for a key that may be marked as X to power y, or Y to power x or just a caret [^]. However to enter a power of 10 such as in the Avogadro Number 6.02*10^23, scientific calculators have a specific key marked EE (enter exponent?) on TI's or x10^x on Casios.
When you use the EE key no 10 should appear: meaning to enter 6.02*10^23 you type in 6.02 followed by [EE] then 23. Press = to display the number. Th e EE key is a shortcut for *10^

### Wrong exponential value

Sorry, but there is nothing wrong with the exponential notation on your calculator. There is however a misunderstanding from your part on the priority rule of operations.
The sequence 0.030377/6.022x10^23 is interpreted as (0.030377/6.022)x10^23 while you wanted 0.030377/(6.022x10^23), dividing by Avogadro's Number.

How to fix it. Enter the power of 10 exponent (10^23) using the EE key. In other words Avogadro's Number should be typed in as 6.022 [EE]23. If you do not have the EE key you must use parentheses to enclose the whole number (6.022x10^23) or use the division key twice /6.022/10^23
On a calculator a sequence a/bxc where both operations have the same level of priority is executed from left to right.

The problem is how to enter the number on the calculator. after it is typed in, you can use in any kind of operations.
To enter Avogadro's number you enter the mantissa 6.02, then you press the [10^X] key then the exponent 23
The [10^X] is on the second row of keys below the [1/x] key. See picture.

### How many grams of aluminum acetate contain 2.24 x 1022 atoms of hydrogen?

1 Look up the formula for the aluminum acetate.
2 Count the number of Hydrogen atoms per molecule: Call that nH.
3 Dividing 2.24*10^22 by nH you get the number of molecules of acetate.
4. Divide that number by Avogadro's Number to obtain the number of moles required.
5. Multiply the number of moles by the molecular mass of the aluminum acetate (look it up or use the periodic table to calculate it), you will get the mass of aluminum acetate that contains 2.24*10^22 hydrogen atoms.

### I need to know how to divide, mutiply, add, and substract in scienctific notation on my Casio fx-300ES

The "problem" is not how to calculate with numbers expressed in Scientific Notation but how to enter a number given to you in scientific notation. Once the number is entered you do not have to do anything special. If you have to multiply it use the (x) button. to add it use the + button, etc.

How to enter a number in scientific notation.

Type in the mantissa (example 6.022)
Press the [X10^x] at the bottom of keypad.
Enter the exponent (example 23)
with this example you will have entered Avogadro's number 6.022x10^23
Other example
1.6 [X10^x] (-) 19 enters the electron charge in Coulombs. The exponent is negative that is why you press the change sign key (-).

### How to use avogadro's number

Hello,
Use the [x10 to x] key, on the bottom row, between [.] and [Ans].
You can store it in a variable (A, B, C or D). You can do that as follows

6.022214199[ x10 to x] 23 [SHIFT] [STO] D stores it in varaible D.

The Avogadro number (Na) is already in your calculator, it is one of the 40 scientific constants, under #24

To display it on screen
press [SHIFT][7] (CONST)
Screen Displays CONSTANT Number 01 tilda 40.
In the space at the bottom right [_ _ _ _] you enter 24. Screen displays Na. Press [=] to enter it in Ans memory so you can use it.

Hope it helps.
