Mathematical Notation and Schools – 5
The Overloaded Equals Sign: Equivalence In this series about mathematical notation and its impact on the learning of mathematics, the previous post started to look at the overloading of the equals sign – so many different meanings and uses cramped … Continue reading

The Overloaded Equals Sign: “Do This Now” In this series about mathematical notation and its impact on the learning of mathematics, we’ve looked so far at the raised minus sign for negative numbers, the various ways of denoting multiplication, and … Continue reading
Mathematical Notation and Schools – 2
Notations For Multiplication In the first part of this series, I looked at the practice in American schools to use a raised minus sign for negative numbers: e.g. ⁻7 for negative seven, in contrast to the “” in 10 – … Continue reading
Mathematical Notation and Schools: The Series
Here’s a summary of the series (thus far) of posts on mathematical notation, with links. This allows you to read them in order, from oldest to most recent. In this series, I’m investigating variations of standard mathematical notation, with an … Continue reading

Notations for negative numbers This blog entry marks the start of a series about mathematical notation and its uses in school. I intend to look in detail at aspects of the standard mathematical notations, and how these help or hinder … Continue reading
First, Do No Harm
Wouldn’t that be a great stricture for Math Education to adopt, just like medical professionals do? Whatever else you do, make sure you do no harm. You’d think that this would represent a really low standard of math education: that … Continue reading
The Whole and the Parts – The Series
