A few weeks ago, I posted a blog about following up worked examples by asking "What would happen to the answer if I changed the question slightly?" Here's another example of this from the blog.

#Mathschat #MTBoS #iTeachMaths #Maths

Initial question:

Find the mean, median, mode and range for the dataset:

12, 13, 14, 17, 17, 19, 20

Answers:
mean = 16, median = 17, mode = 17, range = 8

What would happen if I changed the question?
What would happen if we increased the last number by 1 (20 to 21)?
Which summary statistics would change? Why?
Which summary statistics would stay the same? Why?

"Mon principal guide dans mon travail a été la recherche constante d’une cohérence parfaite, d’une harmonie complète que je devinais derrière la surface turbulente des choses, et que je m'efforçais de dégager patiemment[...]"–Alexandre Grothendieck (1928-2014)

Portrait photographique d'Alexandre Grothendieck, et une citation : "Mon principal guide dans mon travail a été la recherche constante d’une cohérence parfaite, d’une harmonie complète que je devinais derrière la surface turbulente des choses, et que je m'efforçais de dégager patiemment, sans jamais m’en lasser. C’était un sens aigu de la "beauté", sûrement, qui était mon flair et ma seule boussole. Ma plus grande joie a été, moins de la contempler quand elle était apparue en pleine lumière, que de la voir se dégager peu à peu du manteau d’ombre et de brumes où il lui plaisait de se dérober sans cesse."

"My main guide in my work was the constant search for a perfect coherence, a complete harmony that I could see behind the turbulent surface of things, and which I patiently strove to uncover, without ever being tired of it.[...]"– Alexandre Grothendieck (1928-2014)

Photographic portrait of Alexandre Grothendieck, and a quote : "My main guide in my work was the constant search for a perfect coherence, a complete harmony that I could see behind the turbulent surface of things, and which I patiently strove to uncover, without ever being tired of it. It was a keen sense of "beauty", surely, that was my flair and my only compass. My greatest joy was not so much to contemplate it when it appeared in full light, as to see it gradually emerge from the cloak of shadow and mists where it liked to hide constantly."

Theorem of the Day (October 9, 2026) : The Cantor–Bernstein–Schröder Theorem
Source : Theorem of the Day / Robin Whitty

Comprehensive presentation of the "Theorem of the Day", starting with a statement of this theorem.

The Cantor–Bernstein–Schröder Theorem : Let A and B be sets for which there exist injective mapings from A to B and from B to A. Then there is a bijective correspondence between A and B.
