Friedman numbers are numbers that can be made using just their digits, and the / () + - ^ operators. 25 is the lowest, being 5^2 There are just seven such numbers between 0 and 200, 25, 121, 125, 126, 127, 128, 153, It's quite a nice puzzle to figure out how each of these can be made, also, if anyone can be bothered, 987654321 and 123456789 are Friedman, can you find the sum?
