1. Answer: $19890+8716=28606$.
Solution: Obvious remarks: $\Gamma=0, \mathrm{M}=Д+1$.

In the thousands place, the sum $\mathrm{E}+\mathrm{H}$ can end in $\mathrm{H}$ only if $\mathrm{E}=9$ and there is a carry of 1 from the hundreds place.

There is no carry from the units place to the tens place, so Д=1. From this, М=2.

In the word ДЕНЕГ, 4 digits have been guessed.

To make the number as large as possible, let's try 8 for $\mathrm{H}$.

The answer is easily obtained.
