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)
48^2, 9^2, 24^2, 3^2 = 2304, 81, 576, 9.
The digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 can be arranged into an addition sum to add up to almost any total, except that nobody has yet found a way to add up to 1984. However 9 digits can equal 1984 by an addition sum. Which digit is omitted?
Arrange the Numbers 0 1 2 3 4 5 6 7 8 9. so that they sum up to 100. You Can use only + and -
For example for 0 1 2 3 4 sum up to 11
The numbers 1, 2 and 3 have been placed at the corners of a triangle. Arrange the numbers 4, 5, 6, 7, 8, and 9 on the sides, so that the numbers along each side (including the corners) add up to 17.
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.
