If we translate all the letters into numbers, our new sum is 72 ÷ 9 - 1 + 2, which = 9. 9 = L. Interesting number alert! 9 is a square number. In the times tables, it is easy to work out 9 times anything. If you want 7 x 9, take one away from the first number and see how many it will take to make that number up to nine. (6 x 9, take one less = 5, 5 + 4 = 9. Answer 54.) It works every time!
