Puzzle of the Day
These puzzles are also printed in Eight days a week, a booklet published by the Association of Teachers of Mathematics.
If I do something with 2 and 3 I get 11, if I do the same thing with 3 and 4 I get 19, the same thing again to 3 and 7 gives 52. What would I get if I do the same with 4 and 5?
Answer: Multiply the second by itself and add the first so 4 and 5 give 29
