Zahlen

"Zahlen" is the German word for "numbers." In mathematics, numbers are symbols used to count, measure, and identify quantities or values. They include various types such as natural numbers (1, 2, 3), integers (which also include negative numbers), fractions, and real numbers (which encompass decimals and irrationals). Numbers help us understand, compare, and analyze our world, from simple counting to complex calculations. They form the foundation of math and are essential in fields like science, finance, engineering, and everyday life.
