The places or positions of the numbers are based on powers of The places or positions of the numbers are based on powers of Just as, in base ten, the columns represent powers of 10 and have 'place value' 1, 10, 10 2, 10 3 etc. (reading from right to left), so in base 2, the columns represent powers of 2. Hence the number denotes (reading from right to left). Number & Operations in Base Ten In this range, read and write numerals and represent a number of objects with a written numeral.

Consider this: 0 is a non number and you don’t get 9 until 9 is complete so the turn over is at the end of nine and when 10 starts it is just a fraction until 10 is complete which is really just a one again. so the end is at the end of nine or when we actually have nine in possession. so we Have .
