Why is it possible to annex zeros?

Answer 1

Annexing zeros, or adding zeros to the right of a number, is possible because it does not change the value of the number. For example, adding a zero to the end of 5 makes it 50, which is ten times greater, but in contexts like decimal numbers, adding zeros after the decimal point (e.g., 5.0) keeps the value the same. This principle stems from the base-10 numbering system, where each position represents a power of ten. Thus, zeros serve as placeholders that can alter a number's magnitude without changing its intrinsic value.
