The simplest is to simply use the leftmost digit of the number as a special value to represent the sign of the number: 0 = positive, 1 = negative. For example, a value of positive 12 (decimal) would be written as 01100 in binary, but negative 12 (decimal) would be written as 11100.

1,000,000 is how it is represented. In decimal notation each digit has “ten times” the place value as the previous digit. So 25 is 2x10 + 5, ie, 20 + 5 or 25. So one million is 10x10x10x10x10x10.
