Each empty white square in the grid contains one of the numbers 1, 2, 3,..., 8. Each of the horizontal and vertical equations must be true and each number must be used exactly once.
6 ÷ 2 = 3 +____x 1 + 4 = 5 =___ = 7___ 8
Place numbers 1 to 15 in the white circles so that the distance from 1 to 2, 2-3, 3-4 and so on progressively increase each time.
There are four solutions.
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
