I purchased this EL-T100
at an estate sale in Glendora, California, for a dollar (along with
paper). The EL-100T (and the later EL-100TA) is a “Brain
Exerciser”, which is designed to test speed and accuracy on
arithmetic math problems.
There
are three modes for the EL-100A:
Regular
desktop calculator. The display has 10 digits and has the arithmetic
operator indicators. We can set and store the sales tax to use in
future calculations. The keys are fast and responsive.
Quiz
mode: Pressing the [ Quiz ] button to choose from a set of 25
problems, 50 problems, or 100 problems. We are given two results:
the accuracy and the time it took to complete the quiz.
Age
mode: Pressing the [ Age ] button will test you on 25 problems. In
addition to accuracy time, your brain level is measured. After two
attempts, which I took recently (March 24, 2024), I scored 98%
correct in 1 minute, 26 seconds, with the age score of 42. The
second time, I got 96% but in 1 minute, 17 seconds, with the age
score of 40. I just turned 47 last March.

Both sources talk about an updated EL-T100AB, but it is said to
share the same functionality of the EL-T100A.
