Operators, Functions, and Properties – part 35

In the previous post of this series, we looked more closely at the mathematical notion of equivalence, through the lens of operators.   Specifically, we looked at a split (pair) 2|13 and then looked at an operator that turns 2|13 into … Continue reading

Operators, Functions, and Properties – part 34

In the previous post in this series, we looked at some operators that take in two numbers and produce some kind of pair of numbers, an ordered pair, in a way that can be reversed. Here’s another way to produce … Continue reading

Operators, Functions, and Properties – part 29

In this series, we’ve been looking at simple machines where pushing a button invokes an operator that changes the state of the machine.  Stopwatches, coffee makers, calculators are all examples of such machines – some simpler than others.  Many of … Continue reading
