If you’re like me then you’re always trying to fill your day with maths. Here’s something short and sweet that you can do while you wait for the kettle to boil (assuming there are no loved ones around to talk to).
The New York Times are in the process of releasing Digits – a daily maths puzzle (think Wordle’s better-looking cousin).
It’s not a revolutionary concept by any means but it’s worth a look. Here’s one I was given this morning:
I need to use some or all of the six numbers (4, 5, 6, 9, 11, 20) in the dotted circles along with the usual four operations to get to the big number (382).
You can do this in a piecemeal way too! You could multiply 4 and 5 together to create a dotted circle with 20 (there won’t be a 4 or a 5 left). Then you could add 11 and 6 together to create a 17. Then you can multiply 20 and 17 together to get 340. Anyway, this probably isn’t going to get 382; it’s just to illustrate the process.
Actually, this one left me scratching my head for a bit, but I got there in the end. Give it a go yourself!
