If a scientific calculator has an 'EXP' key on it, does that mean that it has expotential operations?

Question

also, how come some are over a hundred dollars and some are around $15?

Answer 1

Actually, in most cases the EXP key is used to enter scientific notation. For instance, keying in 6.02 [EXP] 24 will be displayed as 6.02E24 and will mean 6.02 × 10^24.

The button for exponentiation will typically be either the caret symbol "^", or an x with a superscript y next to it (i.e. x^y, but written properly without the caret).

Typically, the calculators that cost $100 or more are either graphing calculators or have symbolic manipulation abilities, or both. Conversely, the $15 calculators typically only compute elementary arithmetic, the basic transcendental functions (exp, sin, cos, tan, and their inverses), and nothing else. So you really do get more for your money (whether the increase in cost is actually worth the extra features is another question altogether).

Answer 2

7 years old but in case anyone in a hurry gets misled by those later answers it should be said only the first answer and answers like it are correct.

EXP does NOT mean you can input (say) 2 EXP 2 and expect to get 4 out of it. Try it. You'll get 200 for an answer. It simply adds two zeroes. Or you can say it multiplies by 10squared or 100 to give 200.

You can put 10 EXP 2 and get 1000, see? That's how mine works. I have two working like that.

As the first answer said it is a notation thing.

It just enables entering big numbers in scientific notation.

Scientific notation? Writing numbers as A x 10^b. A times 10 to the b power.

So instead of for instance 123,000,000 you just write 1.23 x 10^8

Means 1.23 with the decimal place shifted eight times right and filled with noughts.

On the calculator even easier with that key just write 1.23 EXP 8
and it's done.

Answer 4

Exp Calculator

Answer 5

It means that the calculator can multiply numbers times 10 to a certain power for example if you push 5 EXP 8 then that means you want to enter the number 5 times (10 to the 8th power) The $15 calculators are generally just scientific calculators (Nothing fancy there). Now the ones over $90 those are graphing calculators those are used for Calculus and such that requires calculus.

Answer 6

EXP is the key you push to indicate that the next number is an exponent. That doesn't mean that the Ln and other exponential functions are included.
The more expensive ones are probably programmable (holding extend calculation steps) and may do graphing.

Answer 7

Yes. The exponent key means the calculator has exponential operations.

Not all scientific calculators are created equal. The higher priced units you are finding probably also offer a graphing feature, a paperless tape, and or computer interface.

We are a long ways for the days when I took trigonometry. We had simple scientific calculators that we could use for homework, but all of our tests had to be done long hand... I still have nightmares.

Answer 8

In most calculators, YES, EXP means exponential operation. Regarding prices, some may have the basic arithmethic function that's why it costs less and some have the programable function with full scientific function thats why its expensive.

Answer 9

Yes. The reason some are so expensive are because they do so much stuff and yet are so tiny. The cheap ones don't work as well or do as much stuff.

Answer 10

It means your calculator has EXtrasensory Perception. Hit the button and then try just thinking about your equation instead of typing it in and see what happens.

Haha.. yes, it means it does exponents, and your more expensive calculators allow you to write programs to do routine complex procedures and also have graphing functions.
