This is a number system which uses a base of 10. The valid digits are 0 to 9.
Answer:
Decimal system
Step-by-step explanation:
The present system in Mathematics we use for representing numbers is a system which uses a base of 10.
We write 0 to 9 then next value we shift the digit from units to 10th place and write as 10. Thus we use only digits form 0 to 9, and place values for digits from right are
\(10^0, 10^1, 10^2,....\)
For less than 1 we use decimals and use place values from right to left as
\(10^{-1} ,10^{-2} ,10^{-3} ...\)
Thus the system we use now is decimal system which has base 10.
