The 10bII does not have a key for the common logarithm function. You can use the natural logarithm function (LN, the shifted function of the 2 key) to compute the common logarithm of a number using the relationship

log(x) = ln(x)/ln(10)

In words, calculate the natural log of the value and divide it by the natural log of ten.

SOURCE: CPT button on HP Calculator

You don't need a cpt button on Hp 10ii calculator.You can just press the function button that you want to apply without pressing cpt first.

First of all, the HP 10bII is a financial calculator and does not handle matrices. For all other calculators, you must first create a square matrix, using the Matrix editor. Then you look for the command that calculates the determinant. The syntax will look something like this

det (Mat A) (Enter/=/EXE)

det (Mat A) (Enter/=/EXE)

Press SHIFT [DISP] 4.

DISP is the shifted function of the = key.

DISP is the shifted function of the = key.

The 10BII doesn't do trig and doesn't have functions for converting between degrees-minutes-seconds and decimal degrees. The 10BII+ does do trig but still lacks the conversions.

Solve the formula e^(rt) = 3 , where r=0.06 per time period

(see http://en.wikipedia.org/wiki/Compound_interest#Continuous_compounding for details)

Taking the logarithm of both sides and rearranging gives: t = ln(3)/0.06 = 18.31 time periods. The logarithm function is a shifted function on the 2 button on the 10bii calculator.

You can use the I/YR key on the top row to enter/calculate the interest rate.

It doesn't have one. The calculator keeps track of whether you've hit a digit-entry key since you last pressed a function key. If you haven't, then the calculator computes the value and displays it. If you have hit a number-entry key, it stores the value. Thus, when the book says something like "press CPT then press PMT", you just need to press PMT.

To change the radix point between US and European modes, press shift then [./,] (the decimal point key).

Unlike other brand calculators, HP calculators don't need such a key. After entering the other data, simply press the key for the desired value. For example, to find the future value, simply press the "FV" key.
