Numbers

Numbers are symbols or values used to represent quantities, measurements, or positions. They help us count, measure, compare, and organize information. For example, the number 5 indicates a quantity of five items, while 10 can show a higher amount or a position in a sequence. Numbers can be whole (integers), fractions, or decimals, serving as fundamental tools across all fields—from science and engineering to finance and daily life—allowing us to quantify and communicate information efficiently and accurately.
