Everyone knows that 3 x 7 is 21, but how many people know what 333 x 777 is, without using a calculator? (It is 258,741 by the way.)
If you double that number you get 517,482. Do you notice anything similar about those two numbers? They have the same digits. And I have yet to find another number that, when doubled, gives you the exact same digits, just in a different order.
Play around with a calculator and see if you can find any other numbers like that. Or not.
Check this out:
333 x 444 = 147,852
333 x 777 = 258,741
Those two answers are the same number in reverse! It is just one example of how interesting the numbers 3 and 7 are. The 3rd and 7th notes of a musical scale are the most important ones, and are actually called “guide tones.”
Math is an beautiful thing, because it is exact and it always does what it is supposed to, unlike many things in this world.
