You can put this solution on YOUR website!
The highest order digit should be the largest
number.
So far you have +8%2A100000+
---------------------------------------------
The next higher order digit should be the next
highest number.
So far you have +8%2A100000+%2B+7%2A10000+
----------------------------------------------
The next higher order digit should be the next
highest number.
So far you have +8%2A100000+%2B+7%2A10000+%2B+5%2A1000+
----------------------------------------------
The next higher order digit should be the next
highest number.
So far you have +8%2A100000+%2B+7%2A10000+%2B+5%2A1000+%2B+2%2A100+
----------------------------------------------
The remaining numbers are 0 and 1
The lowest order digit must be 0 to make the number even
----------------------------------------------
Finally you have
+8%2A100000+%2B+7%2A10000+%2B+5%2A1000+%2B+2%2A100+%2B+1%2A10+%2B+0%2A1+
The number is +875210+
