Numbering systems

Abstract

The decimal numbering system makes use of ten digits, as shown in figure 1.1, At school, we were introduced to mathematics by learning ‘hundreds, tens and units’. As shown in figure 1.2, we started in units and were taught to count from 0 to 9 and then start on the tens, having 1 ten and 0 units. Remembering 1 ten, the count continued from 0 to 9, as before, until we reached 9 tens and 9 units. When this point was reached the hundreds column was started.
