Quick Trip: Data, Trails, Formats, Lines, and Graphs Screens
Notice the similarities between the screens and how the same approach
is available with all of them. As far as calculations go. A simple
solution is used here for a simple problem. The full syntax allows a
variety of ways to get the job done. The roulette simulator, for
example, uses direct cell references (e.g. B4) which is the sole
approach of most things called a "spreadsheet." Just got a microphone
so this these videos are getting sound as I go through them.

even most, tables have blocks of rows that are all similar. It's often
the case that these will need rows added periodically. MightMath does a
nice job of making that easy. We're going to look at a table that
calculates the standard deviations for two variables and the
correlation coefficient between them. I am going to clone two rows for
new data. A main
reason MightyMath can do this so effectively is because trails do not
include the sort of specific cell references that leaves you wondering
exactly what you got. BTW, mighty math will update specific references
(e.g. C12) when you insert of delete rows ahead of such a row. If you
delete a cell that is referenced further down the table, it will be
surrounded by brackets producing a syntax error the next time you can
is a tool I am especially fond of. It allows you to walk through any or
all of your trails to see exactly what's happening showing you precise
moments of time in the calculation of your table. You can even see
recent references to cells and memories. The example in question finds
the positive solution to X + X^2 = X^3.
Here's a collection of graphs that are easy enough to make in a moment of curiousity or inspiration.
Things you might not expect could be done by MightyMath:
A table that offers up random multiplication problems
While lines are
mostly for nice print-outs. You can show them (optionally) on the data
screen to direct attention. Also notice in this little application that
messages are put in trails to signal something to the user. A trail is
so much more than a fromula.

greedy is a problem. Watch carefully. As the desired winnings increase,
a wipe out becomes more common because you can cover fewer bets with
the same amount of money. The bets must be bigger.
