Mental math is the ability to perform mathematical calculations quickly and accurately in one's mind without the use of calculators or written notes. It involves using strategies such as estimation, simplification, and breaking numbers down into smaller, more manageable parts. Mental math skills are important in everyday life for tasks such as calculating tips, determining sale prices, and solving basic arithmetic problems without the need for external tools. Practicing mental math can help improve overall mathematical fluency and problem-solving abilities. Some common mental math techniques include the use of number patterns, multiplication tricks, and the ability to perform calculations quickly in one's head.
