For example 6 + 2 = 8 and 62 X 0123456789 = 7654320918 etc. Another interesting (to me) fact is that only the cardinal numbers 1, 2, 4, 5, 7, and 8 rearrange the digits in the number 9876543210.

		Suzanne Hall pose la question : Hi! The other day, two of my students asked a very interesting question: Is the fourth dimension measured with hypercubes?

Space is 3D and is measured with cubes, which are part of space. So, logically, hypercubes would be used to measure the fourth dimension. Chris Fisher lui répond.
