ATHS MAGIC Impress students with your mind-reading maths. 1. Write the number 9 on a piece of paper, fold it, and give it to your students telling them not to look at it. 2. Give your students a calculator and ask them to: Put in their age and add the number of their house. Add the last four digits of their phone number Multiply the result by 18 Add the digits of the answer together. If the answer has more than one digit, keep adding the digits until they only have one left. 3. Tell your students to look at the piece of paper and watch their amazement. The answer is always 9.
