Subtracting Integers Triangle Puzzle #2
• 22 pieces, 27 match-ups
................................................................................................................................

Note:
• The expressions have 2 terms.

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.
