## Operators, Functions, and Properties – part 22

In this series, we’ve lately been modeling a four-function calculator as a state machine.  A state machine moves from state to state based on operators that are invoked through button presses.  Operators  take their input, do something with it, and … Continue reading

## Operators, Functions, and Properties – part 21

In this series we’ve been looking at operators, which we have visualized as boxes with a value (or multiple values) going in, and a single value coming out.  We pictured these boxes as little machines, which sit there waiting for … Continue reading

## Operators, Functions, and Properties – part 20

In this series, we started out by looking at operators as little boxes that have a value going in and a value coming out, and that can be chained together in interesting ways, ways that allow us to illustrate key … Continue reading

## Operators, Functions, and Properties – part 19

In this series, we have been playing with the notion of a state machine: a machine that changes states depending on what buttons are pressed, and this has led us to look at the mathematics of operators in an interesting … Continue reading

## Operators, Functions, and Properties – part 18

In the latest post in this series, we looked at modeling a simple four-function calculator as a state machine where key presses invoke operators that operate on the current state of the machine, producing a new state. Missing from this … Continue reading

## Operators, Functions, and Properties – part 17

In this series we’ve been looking at machines with buttons, where a button press will invoke an action which we’ve called an operator.  The operator operates on the state of the machine.  It should be interesting to analyze the workings … Continue reading

## Operators, Functions, and Properties – part 16

In this series, we’ve been playing with operators in an attempt to make some models for an introduction to algebra that may fit modern kids’ ways of thinking better than some traditional models. A key entry point for us has … Continue reading
