First, next Friday I am speaking at a special conference for A-level students on science and pseudoscience. If you are a teacher or a student or even a normal person, and interested in coming along, the details are here.
Second, here is the Friday puzzle! A simple one this week, can you make the following equation correct by moving just one number…..
62 – 63 = 1
As ever, please do NOT post your answer, but do say if you think you have solved it and how long it took. Solution on Monday!
