**Inside Your Calculator**

Here are new applications associated with * Inside
Your Calculator*:

The algorithms **BIGMULT** and **BIGDIV**
are developed through comparison with our standard decimal algorithms for carrying
out similar procedures with one and two-digit numbers. This provides insights
into the important and rarely explained bases for these procedures.

The program** ****BIGMULT**,
which also appears as **Inside Your Calculator
****Appendix L**, describes in detail
a program that will give you the ability to multiply numbers with products of
up to 400 digits. You can use TI Connect software to download the program to
your calculator from bigmult.

The program** ****BIGDIV**
extends the ideas of **BIGMULT** to division, The resulting program will
handle calculations whose divisor, dividend and quotient may each have up to
400 digits. You can use TI Connect software to download the program to your
calculator from bigdiv.

The program **BIGDIV** can be very slow, however. The reason:
correcting the partial quotient when it turns out to be too large is done by
reducing the trial quotient one at a time. With large numbers this can slow
the process considerably. A way around this is described in Donald Knuth's * The
Art of Computer Programming*, volume 2 (
