Wonderful! Nicely done and really funny. Wait till my students see both answers tomorrow! Thank you!
I agree on the funny aspect. Answers are really interesting. One of my students said: "Teacher, 625 square meters is larger than my flat. Is it possible?" So, Maths is magical after all! All my life refusing the subject and what I was really missing was fun and magic. I must deduce teachers are important!
This is a big compliment for all of us Maths teachers here! Thank you.
