I started writing down all the multiples of 3 from 1-9 as the letters represent a single digit. Then I started to work out e x 3 =? First I worked out what multiplied by 3 = _1 as obviously it couldn’t have just been 1 as there is no multiplication by 3 that equals 1. 7 x 3 = 21 so I managed to find that e = 7. Then the answer of 3 x d = _7 so d = 5 as 5 x 3 = 15 and then add the remaining 2 that were carried over from 21. I repeated that method throughout the question until I got my answer.
