How did you arrive at this lowly number of 240?. Did you actually count them? Did you use them all? Some may be accessible through a specific sequence of key presses and for that you will have to read the whole manual.

Your calculator contains physical constants (and there is bunch of them). It can do conversions between units and back. Each physical unit and each conversion in one way is a function.

If your calculator is defective you will have better luck detecting the defect by thinking about a function that you want and verify if your calculator has it.

To distinguish themselves from competitors manufacturers make many claims and the claimed number of functions is one such point they try to emphasize with the consumers. No one can easily verify the claim unless one knows what the manufacturer calls a function. (remember these are not mathematical functions but functionalities (capabilities). Having two line display may be one of them and so is the replay.

On a fx-991MS? With many other models, including the fx-991ES, I'd say you have the calculator in binary mode but the 991MS doesn't have such a mode.

For common antilog, use 10^x, the shifted function of the log key. For natural antilog, use e^x, the shifted function of the ln key. In either case, press the appropriate function and then enter the expression whose antilog you're seeking.

Your calculator knows only the decimal logarithms log or log_10 and the natural logarithms (ln or log in base e).

So you cannot compute directly the logarithms in any bases other than 10 and e.

A workaround consists in using the relation

log in base b of a number a (log_b (a))

log_b(a)= (log_10(a) ) / (log_10 (b))

or the relation

log_b(a)= ln(a)/ln(b)

log_2(0.3)=log(0.3)/log(2) where log is log in base 10

Similarly

log_2(0.3)=ln(0.3)/ln(2)

As to the multiplicative factor you had at the beginning of your expression, just multiply the value obtained by one on the formulas above (both formulas will give the same result) by 0.3

how to solve probability in fx-991ms

Hello,

If by calculus problem you mean derivatives of functions, integrals, extrema and such things, I am sorry to inform you that neither the Casio FX-300MS, nor the FX-991MS can handle them. The newer Casio calculator FX-991ES is capable of performing numerical differentiations and integrations. There also graphing calculators by Casio FX-9750G, FX-9860G as well as by Texas Instruments (TI 83 PLUS/TI84PLUS) that are reasonably performant in that area.

Hope it helps.

In any scientific calculator log2(n) can be calculated with either ln or log function as
follows

Log2(n)= ln(n) / ln(2)

Or

Log2(n)=log(n) / log(2)

both will give nearly the same answers

Log2(n)= ln(n) / ln(2)

Or

Log2(n)=log(n) / log(2)

both will give nearly the same answers
