7 days later it is again the same day of the week, so it is convenient to define a new number system in which
7 = 0. It turns out that you can do arithmetic in this new number system in the same way as in the ordinary number system.
If 7 equals zero, you can subtract 7 and still have the same number. So:
10 = 3
If you square both sides:
100 = 9 = 2
multiply both sides by 2:
200 = 4
Now, if you remember your multiplication tables, 63 = 9*7 = 0. Therefore 263 = 200 = 4
This means that 263 later it will be 4 days later in the week, i.e. Friday.
