This has been doing the rounds on the Internet recently.
This problem can be solved by pre-school children in five to ten minutes, by programmers in an hour and by people in higher education ….well, check it yourself!
I’m pleased to say despite my various Maths degrees I solved the problem quickly!
I obviously have the mind of a pre-schooler!
You can find a hint then check the answer here.
I present the problem as posed everywhere – though it looks like a misuse of the = sign!
Only put an equals sign between equal expressions!
