In the expression TWO * SIX = TWELVE, each letter E, I, L, O, S, T, V, W, and X represents a different digit 0 to 9. Find all three solutions.

The problem does not specify this per se, but assuming non-leading zeroes there are exactly three solutions and these are as follows:

(TWO, SIX, TWELVE) = (345, 986, 340170),( 165, 972, 160380, and (218,965,210370)
