# Mathematical Place Value

Our number system (Hindu-Arabic) has ten familiar digits, 0 to 9. Numbers higher than 9 are made using place value, which assigns a digit a greater or lesser value depending on where it shows up in a number. For example, 3,000 + 600 + 10 + 9 + 0.8 + 0.04 + 0.002 = 3,619.842.
