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

SOURCE: how to clear the memory key on Texas instrument

Hello,
Your calculator has 3 memories (M1, M2,M3)
To store the number 170 in M1 use 170[STO]1
To recall a number from M1 use [RCL]1
To add a number to the content of M1 [2nd][SUM]1 (adds displayed value to contents of M1).
[2nd][EXC] 2 exchanges the value already displayed with the contents of M2:

To erase (clear) a memory register, just store 0 in it.

Hope it helps.

SOURCE: how do you make the calculator ti 30xa convert

I have a few questions and then I should be able to help you. In the equation you want to solve there is a letter g. Is this supposed to be there? Does this represent units such as grams? If this is the only units in this equation the answer will be mass not volume. Lets ignore the units and just punch in the numbers. Assuming the equation you want to solve is 3.70/2.50 x 10^-6. The buttons you need to push are 3.7/2.5 EE 6 [+/-] =. The EE button is the exponent button and the [+/-] button is the change sign button, located just below the 3. The change sign button changes the sign of the proceeding character, in this case it changes the 6 into a -6. This calculator will calculate the exponents before it does the multiplication or division so you don't need to use any parentheses for this equation. I hope this helps you out.

It is a generic scientific calculator and not feature rich. It can calculate trigonometric functions, exponentials, logs, powers, combinations and permutations. You must have an idea about what you are calculating in AC circuits and figure out, by reading the manual, what calculations can be performed on this basic scientific calculator. The manual is available online at education.ti.com

How do I do exponents on this calculator?


Two keys can be used to enter negative exponents on the TI-30Xa scientific calculator; the [y^x] key or the [EE] key. The [y^x] key is used for all exponents while the [EE] key is used for scientific notation only.
The examples below will demonstrate how to use both keys:

1) Entering 7^-2.

• Press [7] [y^x] [2] [+/-] [=].
• The calculator will display: 0.20408163.
2) 1*10^-3.

• Press [1] [EE] [3] [+/-] [=].
• The calculator will display: 0.001

HELP, I can't seem to figure out scientific notations with my Texas Instrument TI-30XA. I've searched for hours on the web. Here's the problem: 7.82 x 10^10 / 63.55 = 1.23 x 10^9. But when I input 7.82 x...


Hello,
The error comes from the lack of understanding of the meaning of the notation used by the calculator manufacturers.
The [EE] is a "shorthand" notation for times 10 to the power of .
To convince you of it try entering

1[EE]0 [=] this is 1*10^0=1*1=1
1[EE]1 [=] this is 1*10^1=1*10=10
1[EE]2 [=] this is 1*10^2=1*100=100


When you enter 7.82x10[EE]10
you are calculating
7.82*10*1*10^10=7.82x10^11.

Hope it helps.

One solution that you might try is to put the scientific numbers in parentheses. For instance open parenthesis, type in the first scientific notation then close parenthesis, next hit the divide key and then open parenthesis and type in the 2nd number in scientific that you are dividing by and then close parenthesis. Hit enter or =. I'm not sure if this will fix your problem, but it is worth a try.

Inputing Scientific Numbers


If you mean using the "EE" key it's straightforward.

To enter scientific numbers, enter the number, then press EE, then the exponent value. The TI-30XA will stay in scientific display until you "clear" or turn it off. It will also switch to scientific notation if you multiply big numbers that exceed the display.

E.g. Input 3, EE, 10, X, 3, EE, 10, =, gives you the answer 9 times 10 to the power 20. Press the "square root" key and you will get back 3 times 10 to the power 10.

You can mix entries too, e.g. 3, EE, 10, X, 2, =, gives you 6 times 10 the power 10....
