Box Progression Part 2Logic Level 1
\[ \large \square + \square\square+\square\square\square+\square\square\square\square \]
Place each of the digits 0 through 9, without repetition, in the boxes above. Then what is the maximum possible sum?
Details and Assumptions:
- This is an arithmetic puzzle, where \( 1 \square \) would represent the 2-digit number 19 if \( \square = 9 \). It does not represent the algebraic expression \( 1 \times \square \).
