We recommend you donate to mathematics education.
The Temple of Mathematics site is run for the public. If you like it and want to see this site stay operating, you can donate to help cover its cost, a significant cost to run on a reasonably fast server. If you want some/all, or 50% each, to go to Math Hero (for content) or Matheros (for design) please add a note.
