16-1112345678910111213141516ZeroMost of us use the system of numbers with numbers from 1 to 9 and 0 (zero). With these ten numbers, we can write any number from the biggest to the smallest. The Indians first invented and developed the 1 to 9 system of numbers. They then invented the zero. This was a very important invention because it made it easier to write big numbers and to calculate.16-12123456789101112131415160Ask and answer the questions :?What is the system of numbers made up of?
