Assuming that none of the numbers contain any leading zero, it can be observed that none of the alphametics: LEVEL+LEVEL = AWESOME or, LEVEL+LEVEL+LEVEL = AWESOME possess any solution. In other words, when LEVEL is added twice (or thrice), it does not equal AWESOME. (Each of the capital letters denotes a different base ten digit from 0 to 9)
(i) What are the respective minimum and maximum number of times that LEVEL can be added to make AWESOME?
(ii) What further solutions are there for (i), assuming that the numbers can contain leading zeroes? Of these additional answers, what are the respective minimum and maximum number of times that LEVEL can be added?
The minimum number of LEVELs added together to equal AWESOME is 37.
AWESOME = 1786508; LEVEL = 48284.
The maximum number of LEVELs added together to equal AWESOME is 575
AWESOME = 9056825; LEVEL = 15751.
An additional five solutions are possible if leading zeroes are permitted, giving a total of twentyseven solutions. The respective maximum does not change, but the minimum is reduced to two LEVELs:
AWESOME = 0148694; LEVEL = 74347.
