What times what equals 206?
Well, isn't that a happy little math question! Let's see, we can break down 206 into its factors: 1, 2, 103, and 206. So, 2 times 103 equals 206. Just like painting, sometimes we need to look at things from a different perspective to see the beauty in the solution.
What characterizes binary system?
In normal counting (termed Arabic notation) each digit position is greated than the one to its right by a factor of ten. So 2045 is 1x5 + 10x4 +100x0 + 1000x 2 Another way to show the same sum would be: 100x5 + 101x4 + 102x0 + 103x2 In binary we use 2 instead of 10. We only need the digits 1 and 0, just as with normal numbers we don't need any digit higher than 9. So 1100100 would be: 20x0 + 21x0 + 22x1 + 23x0 + 24x0 + 25x1 + 26x1 We can work out all those powers and we get: 1x0 + 2x0 + 4x1 + 8x0 + 16x0 + 32x1 + 64x1 That simplifies to: 4 + 32 + 64 = 100
