Choose n consecutive positive whole numbers, for some value of n. Multiply your numbers together. Is the answer a multiple of n! (Oh no, now I'm stuck because I want to write "n factorial question mark" but it will look weird. I guess I'd better redraft it. Or just post it and hope for the best)

Choose any five consecutive positive whole numbers, and multiply them together. Did you get a multiple of 120? Will you always get a multiple of 120? How would you convince someone?

Day one of big #Mathsjam has been a big overwhelming blob of fun and also overstimulation. I'm running a Circle Theorem Badges table this evening helping people make badges with their favourite circle theorem on. And then hoping to chill out with some craft - I'd love to go to Mathsjam Jam but I suspect it would be Too Much 🙁

A little #NoticeWonder for you.My wondering was this: what other patterns could I make with these tiles?

Here's a question that I'm interested to know how people will answer:

I'm travelling by car. If I drive for half the journey at 60mph and half the journey at 40mph, what will be my average speed for the whole journey? How did you work it out?

I just got caught out by a fence post error! I'm currently sewing together blanket squares, and I cut off lengths of yarn long enough to do two seams, and got really confused that I had half a length left after joining eight squares, and it took me a beat to realise eight squares meant seven seams

As a mathematician, one reason I find it hard to keep my house tidy is that tidying up involves categorising things. Some of these decisions are easy - books belong on shelves, non fiction organised by theme, fiction alphabetically by author. But some decisions are hard, and this is why traditionally most houses have drawers for 'bits and bobs' - stuff that isn't easily categorised. Most of my house is currently bits and bobs 🙁

Best bits: hanging out with my favourite maths humans; teaching people about Geogebra, making badges with circle theorems on, making a paper robot that waves its arms when you clap, making flexagons, contributing to the community blanket, meeting so many like minded people, feeling acceptance and warmth and not having to pretend to be someone I'm not but being my authentic self for four whole days

Had an incredible time at #EMFcamp #EMF2024. I am slowly readjusting to being back in the real world, and my body is slowly recovering from 4 nights sleeping on the floor with loud sounds slightly muffled by earplugs, eating random stuff at random times, walking a lot and being constantly either too hot or too cold...

When my beloved and I come to McDonald's I always get one barbecue sauce and two ketchups to share. We each choose complete sauces rather than both dipping in the same cup.

How many different ways can we divide the sauces? What other mathematical/combinatorical questions could you ask while waiting for your special order (no onions) to be cooked?
