  • The expressions have 2 terms.
  • The differences include numbers from -13 to 13. No differences repeat.
  • The numbers -19 to -14 and 14 to 19 are used along the rim.

Some Tips:

  • The text is read along the outside of the triangle. If you rotate your triangle, you will easily be able to read all of the text right side up.
  • For every spot that the triangles match up, the expression and answer must match up.
  • When two triangles are touching (share a side), they must be a match.
  • There will be expressions and solutions that are not used. They will end up along the outer rim of the puzzle with no match.
