Numbers
In addition to text computers must store numbers
Numbers are sometimes stored as text characters:
0100 0110 0100 1001 0101 0100 0011 0001 0011 0000 0011 0000
Mostly numbers are stored directly using binary notation, since it has only two digits, 0 and 1
Binary numbers and arithmetic are very much
like decimal, except restricted to the two digits
0 and 1 … what number is 1100100?
Binary is counting on your fists instead of your fingers
