Question about Texas Instruments TI-30XA Calculator

Ad

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=11[EE]1 [=] this is 1*10^1=1*10=101[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.

You can put it in scientific notation by hitting 2nd and 5. It will put your answers in scientific notation and not round that particular answer you have.

On a TI-30XA the EE key is just above the 7 key.

On a TI-30XIIS the EE is the shifted function of the key just above the 7 key.

To enter powers of 10 as in scientific notations use the EE key.

To enter 13x10^6 type in 13 EE 6 =

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.

It's been a while since my TI calculator died, but I think you can just hit EE (may be "exp" on your model) followed by =.

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

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....
