Depends on where your calculator wa made. On my made in China model there are two screws under the batter cover and screws under the rubber feet. Peel these off carefully and you can glue them back into place after you are done.

WHAT IS USED FOR THE EQUAL TIME


The calculator is doing exactly what you tell it to,

You first input 1.06. Then you press the y*x key, which tells the calculator to raise the previous number on the stack to the 1.06 power. Then you input 10. The result of all this is 10, as your calculator shows.

If you want to raise 1.06 to the tenth power, press 1 . 0 6 ENTER 10 y^x.

My 12c shows 1.7908 for the above.

Cpt button 12c calculator


Unlike TI calculators, the HP 12c doesn't have or need a CPT button. It knows whether you've made a numeric entry or not. To calculate N, I, PV, FV, or PMT, simply press the appropriate key without entering a number.

Do you have advice in calculator choice between HP 12 c and the TI BA II Plus Professional Financial Calculator? Assuming that I get proficient with RPN (which I'm learning now); is one faster than the...


The 12C is more expensive and more powerful than the BAII+Pro. The HP is also programmable, which the TI isn't. Starting from scratch (assuming you've never used a calculator before---a somewhat unreasonable assumption) the TI might be easier to learn, at least initially. But after a certain point, the HP will leave the TI behind. The HP is faster and more capable.

There are at least three different versions of the 12C available. There's the original 12C, the 12C Platinum, and the current 12C. The only way to tell the difference between the two non-Platinums is to look at the battery compartment---the original uses three button cells while the newer uses two coin cells. The newer one is MUCH faster. The Platinum, however, can use RPN or algebraic.

Unless your choice is limited to the 12C or the BAII (by the requirement of an exam, perhaps), you might want to look at the HP 20B and the HP 30B. Programmability aside, they're even more powerful and easier to use and faster than the 12C, and the 30B is also programmable.

There are other considerations, of course. Factors such as the feel of the keyboard, the 12C's landscape orientation as opposed to the others' portrait orientation, etc, are all matters of personal preference.

Disclaimer: I own multiple HP and multiple TI calculators. I tend to use HP calculators for calculating, while I use TI calculators to answer questions here at FixYa.

The display shows comas and misplaced decimals instead of properly placed decimals. For example 4258.32 reads as 4.258,32. How do I fix this on the HP-12c calculator? Thanks


Press and hold the decimal point key then press and release the ON key to swap the radix marks between US and European modes.

My decimal changed to a comma, how do i change it back?


Hi,

P12c display from Comma to Point This document describes how to change the display of the decimal point on the HP 12C (HP12C) Calculator from a comma (commas) back to a decimal point.
Instructions
  1. Turn off the calculator.
  2. Hold down the decimal point.
  3. Continue to hold the decimal point key, while turning on the calculator.
The comma should change back to a decimal point.
Explanation The comma is the European equivalent of the decimal point.
This procedure is also applicable to HP12CP (Hewlett-Packard 12c Platinum) and HP12CPA (Hewlett-Packard 12c Platinum 25th Anniversary Edition).

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

How can i tell the difference b/w hp12c and hp12p. i bought a hp12p from ebay(it's a stupid decision, I know!) and when i solving for IRR, i felt its running quite slow. I think the guy sold me the hp12P...


I couldn't find any reference to a HP calculator model 12p.
There is a HP 12c financial calculator and a 12c Platinum financial calculator.
Check both models (for images, specifications, functions, user guides, etc.) :

Incorrect claculation


I get an answer of 366.91 in my 12C as well. You might try either putting in a zero for FV before hitting the [PMT] key, or clearing your registers before doing the problem, as you may be picking up an old value from a previous problem in the FV register.
