Seems a good day to remark that π isn't something to get all bothered about, but then neither is τ. At least, not *that* τ.

The arrangement of squares is as follows: Taking point A as the origin, with the squares building upwards from the first row. 2 squares on row 1, where A is the bottom left corner of first square. 2 squares on row 2, starting above the 2nd square of row 1. Point B is the bottom right corner of the 2nd square of row 2. 1 square on the row 3, above the 2nd square of row 2. 3 squares on row 4, with the middle square above the square of row 3. 1 square on row 5, above the 1st square of row 4. Point C is the top right corner of the top square.
Here is today's #OCRMathsPuzzle.
Several square blue tiles with side length 2 m are arranged as shown below.
Points A, B and C are marked on vertices of the tiles.
What is the area of the triangle ABC?

Not maths but I'd appreciate input from my mathematical friends.
What do you do when life is tough, what brings you out of a period low mood (or at least helps you manage it)?

An arrangement of seven squares. Six of the squares are identical and are arranged so that reading from left to right they form three stacks that abut and are of heights 2,3,1, with each base square aligned with the second square in the stack to its left. A tilted larger square overlays the six and shares a vertex with the lower right vertex of the bottom-most square. The top left vertex of the uppermost of the six squares lies on an edge of the larger square. A line is drawn from the left-hand vertex of the larger square to the lower right vertex of the rightmost small square. The angle formed by this line and the left-hand edge of the larger square is marked with a question mark.

Anyone know what this is called? Is it a thing?! Found it in Bīrūnī from the 11th century ... as one does.

On the left is a blue background, with the Gaelic text Gabh pàirt ann an Seachdain Matamataig na h-Alba! in large white letters. Below that the hashtag #MathsWeekScot and the Maths Week Scotland logo. On the right is an illustration of the Maths Week Scotland mascot, who wears oversized blue glasses and has a yellow head and long pink and yellow striped arms and legs. Behind him is a background of trees, plants and flowers.

Interestingly, xf actually makes a lot of sense as notation for the value of the function f at the point x.
A function goes from its domain to its codomain so f sits *after* the domain. Hence, xf.
If we do f *and then* g, we write that as xfg. Which is obviously correct.

An except from the UK government a level maths specification showing the notation for ordered pairs, (x,y), and for open intervals, (a,b). Between them are notations for closed and half-open intervals.
Now *that's* not confusing at all!
@vmnalex.bsky.social
(Admittedly, both notations are correct, but it's a clear example of the point that notationis insufficient)

Person 1: "Well, actually" Person 2, thinking: "Aww hell, here he goes again..."
Been meaning to get to this one for a while.
There's so many niche mathematical notation quirks that come up and appear differently in different places, sometimes it's hard to tell what the intended notation is meant to be!

This is a first attempt at categorising @catrionaagg.bsky.social 's puzzles by the techniques used to solve them.
My hope is that this makes it easier to use them in class.

I’m thinking of buying a visualiser … either an IPEVO DO-CAM or an Innex DC500. If you use either of these I’d love to hear your views of them … particularly any shortcomings.

Great to see @jamesmunromaths.bsky.social and @oxfordmathematics.bsky.social offering TMUA prepartion sessions. Private tuition can make a big difference with these tests and anything to help level the playing fields is welcome.
