Question:Write nine hundred fifty eight in standard form:

Answer: 958.

Write the standard number 67 in words:

Answer: Sixty seven.

Explanation: The decimal numbers we write are the standard form of numbers.  There are so many other type of representing numbers. Ex: Roman numbers, expanded form, writting numbers through words, binary number,scientific number.

The reason for the decimal number to be called standard as  I believe is its simplicity for all types of calculation and its popularity all over the world. Compare the how you multiply 56*65 in standard form and roman number system.
