Tens are a numerical value that represents ten units. In mathematics, they are often used as a base for counting and organizing numbers. For example, in the decimal system, each place value increases by a factor of ten, making it essential for calculations and understanding larger numbers. In everyday life, tens can be seen in various contexts, such as in money, where prices are often rounded to the nearest ten, or in sports, where scores may be grouped in tens for easier tracking. Understanding tens helps in basic arithmetic and enhances numerical literacy.
