Sketch from Programmers At Work, Microsoft Press, (c) 1983

This product has its roots in one I created in 1979 and another in 1991 (i.e., ancient PC history). In January (2020)

an automatic Windows update destroyed the XP partition where I could still enjoy these tools. Well, I could not bring

myself to use a traditional spreadsheet. This approach has met all my math needs for the last 40 years. So I decided

to unretire and create an update incorporating advances in equipment and development environments as well as

modernizing the interface. You are welcome to add T/Maker to your Mac or Windows menu.

T/Maker offers the ease of use and conceptual simplicity of a hand calculator over two dimensions. Many may never

use it for more than arithmetic across rows and columns, but that is what most people do most of the time.

Being perfectly blunt:

I find algebraic formulae: tedious, mistake prone, too much typing, and a constant reminder of Bingo. |
I find calculation trails in separate cells: intuitive, quick, and fun! |

"And wait," as they say on infomercials, "there is even more!" Please don't jump to any conclusions yet.

T/Maker is a java desktop application for Mac and Windows computers. It makes no connection to the internet

when used. There is no self-updating, tracking, ads, or any sort of pestering or spying. All your data is kept on

your machine. It should run for the next 30 years under java. I will not be doing any marketing. I do hope some

adventurous souls who happen onto this page will give T/Maker a try and find it useful in their lives. And if so,

I hope they will pass the link on. Feedback is always welcomed.

The videos are amateurish and one day I will redo them. But luckily T/Maker is easy to grasp and you can put it to

work after a few minutes. I want to move on to redoing my word game which will appeal to a wider audience.

If you have a touch screen (Windows 10), it is amazing what you can do with T/Maker using just one finger while

on the sofa. Of course, everything can be done with a keyboard along with a mouse or touch pad.

This one uses a mouse. There is some overlap with the above but fresh material as well. Video 1

I would like to say a few serious words about learning math with T/Maker. Students who know arithmetic can build

their problem solving skills along with an introduction to data analysis, statistics, logic, and graphics years before the

7th or 8th grade. And that will help close the thinking gap between apples and oranges arithmetic and algebra.

That's a leap that comes out of nowhere and many have difficulty accomplishing it. Building confidence and feeling

comfortable using math to solve problems is a T/Maker specialty. It's also what math educators say about getting

better at math--USE IT ! Kids can do it for their own problems with a tad of help getting started.

The image below shows elements you may use when building calculation trails. There are a few notations here that are particular

to T/Maker's approach and fit well with it. But much is just the application of basic arithmetic with operators, constants, memories,

and functions you could do with a variety of hand calculators. However, that would be incredibly more laborious, and you would

have no record of what you specified. You don't need to learn what you don't need to use.

Video 2: The syntax is on the table

Memories, I should point out, introduce the notion of names or letters representing values (algebra) under the easiest to understand

circumstances. You pick the name and you put the value in it. Memories also provide incredible economies in specifications.

Here are 48 values calculated by one simple trail. This is practical math taken to a whole new level.

Video 3: Memories are made for this

The Combo Cursor is a cursor that performs a variety of calculations as it proceeds in a trail and stores the results in memories

where they can be easily fetched. Among the values are the minimum, the maximum, the mean, and the median. These

are some elementary members of what you might call statistics and data analysis. There's a standard deviation too and an

example table of calculating a correlation coefficient. The video also includes changing some formats, a sort, and making

a stacked bar chart. It's all easy.

Video 4: A multi-tasking cursor

One of the very nice things about T/Maker is that it

can clone rows incorporating all elements of a model

row. Many tables have a block or blocks of rows that

are identical in terms of the calculations and other

elements they require. This feature is great for building

a table over time.

Video 5: Another row for the road

As a programmer, I know that no syntax or language is complete without a tool to debug the work

you have done. Here's is one for T/Maker's unusual way of writing calculations. It's a way to find

mistakes or just review how things work and fit together.

Video 6: A walkabout on trails

I want to nip in the bud the notion that T/Maker might be only a toy suitable

for youngsters by showing (without a lot of explanation) a table that runs a

simulation of the optimal strategy for playing roulette. That strategy works from

the amount you want to risk and what your want to win. It bets on single numbers

with increasing bets until you go broke or hit one number. At your first win, you

have achieved your goal. It also allows me to make some meaningful contrasts

between trails (T/Maker) and formulae (spreadsheets).

Video 7: Yes, I can!

Before getting back to more meat on how you contsruct and use trails, I did want you to see that you can import

and export data to other cell based programs or even pick data up from web pages in some cases. This might

hopefully encourage you to try T/Maker since you can start with data you already have or transfer data from

T/Maker to another program if so inclined.

Video 8: Well, Hello Data!

You have already seen the Lite Assistor for trails, this video explains its big brother.

Note that the math functions are there to tackle geometry, trigonometry, exponentials, logarithms, and there is a random number

generator for simulations. Mortage payments, present value, and growth rates are also built in with an easy to use approach.

Video 9: Big Brother

I wanted to show you one other assistor that is handy if a logical test is needed to direct calculations that should

only be done under certain conditions. It's called a WHEN clause. In the video you will see how to construct one

and another usage which can be handy for finding data entry errors or just counting instances of various values

in a column of a table.

Video 10: When WHEN

I would not say entering and editing data is much different from other cell based programs. But you will

see a nifty way to get to locations in your table or make use of abbreviations.

Video 11: A little gift for terrible typists

While the charts and graphs are not on a par with well-established spreadsheets, you can use them to get insights into your data

and a student can learn what type of chart best illustrates a certain point.

You can easily print your tables. Here is the print box for that. It tells you how many pages wide and pages long it

will be. You can reset the parameters that affect the size and recalculate. If you are just interested in keeping historical

paper records, you can save paper and ink this way. You can also make some nice forms, not that I want to contribute

to the number of forms in the world though I would like more space to actually write the address! Here's a (scanned)

invoice printed with some lines and a typo.

.

I believe T/Maker is easy to learn and hard to forget. The tools you will need for various tasks are at the top of the screen, so you won't

have to search for them in pop-up or drop down boxes. The interface is consistent across all functions/screens. You will find it

worth firing up for even just a few numbers and calculations.
