Then, 5 ☆ 4 = , which you may recognize as two components of a different Pythagorean triple. What a coincidence! The final expression simplifies to give an answer of *3*.

*Note: *I apologize for changing these math problems when I give the solution, but you can imagine how creating a unique, creative, and solvable math problem in the ten minutes before school can lead to interesting mishaps! Anyway, I hope these problems are useful for you.
