This might be a can of worms, but it seems like an interesting one.
What's the difference between a "trick" and a "clever strategy" in math?
If I compute "4% of 75" by rephrasing it as "75% of 4", is it a "trick" or a "clever strategy"? Why?

Attention @kesbath Cipher Challengers! It may be half term but the @Cipher_Challenge is still happening! Challenge 3 was released yesterday so don't forget to try and decrypt it before school starts again! (It's not too late register too!) #codebreakingneverstops #cipherchallenge
2 more days til the final practice challenge comes out & you'll have 2 weeks to finish it as we are allowing for 1/2 term. After that things get serious! Will Jodie evade Harry? Is she even trying to get away? And what did happen in the vault? Find out at cipherchallenge.org

ALT The picture shows multiple laminated circles. There are two different sizes, the larger circles have the letters of the alphabet in black around the outside. The smaller circles have the letters of the alphabet in red around the outside. These will be placed together to form a wheel used to code or decode messages.

Doors closed 2.5 hours ago. We are, as ever, staying late. There have been reports of a thesaurus leak, and we are worried, bothered, concerned, apprehensive, fraught, fretful and nervous about it. You never know when it may strike. Or transpire. Be vigilant. And wary.
