Then "wonderful+mathematics+garden" =2 15.

To minimize the "wonderful mathematics garden", we must minimize the "beauty" and arrange a large number of mathematics and gardens as much as possible.

And "number" comes before "flower", so "number" is smaller than "flower". So "number" is 8 and "flower" is 9;

Similarly, "learning" is in front of "garden", so "learning" is smaller than "garden", so "learning" is 6 and "garden" is 7;

So "wonderful" =2 15-97-86=32.

Therefore, the minimum number of "Wonderful Mathematics Garden" is 328,697.
