Arrange all the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 to give four different square numbers. (You make a square number when you multiply something by itself, so 49 is square because it is 7 times 7)

1 2 3 4 5 6 7 8 9 = 100
Challenge:
Place + and - math symbols between the numbers above to make the equation true.
Use + and - a total of three times.
Do not rearrange the numbers.
