The value of a digit when expressed in expanded form of the number is called its place value in the number. Thus, the place value of a digit in a number is the value it holds to be at the place in the number. ... In the number 2137, 2 is at Thousand-place, 1 is at Hundred-place, 3 is at ten's-place and 7 is at one's-place.

Understanding place value is important because it helps you understand the magnitude of numbers. Because of place value we know 30 is 10 times bigger than 3 which is a hundred times bigger than 0.03. This would not have been possible with Roman Numerals as they do not have a decimal point, or zero for that matter.

A zero is obviously more than a place holder if it doesn't fall at the end of a number. For example, the zero in 405 is significant. Thus, If a zero is found between significant digits, it is significant.

Place value is important because it helps you understand the meaning of a number. If people just used numbers randomly, no one would know which numbers people meant. You need place value to understand the order of numbers as well.

The difference between variables and constants is that variables can change their value at any time but constants can never change their value. (The constants value is lockedfor the duration of the program). Constants can be very useful, Pi for instance is a good example to declare as a constant.

An exact number has a value that has no uncertainty associated with it. Exact numbers occur in definitions, in counting, and in simple fractions. An inexact number has a value that has a degree of uncertainty associated with it. Inexact numbers are generated anytime a measurement is made.
