mental arithmetic

Mental arithmetic refers to performing calculations in your mind without using physical tools like paper, a calculator, or a computer. It involves process as estimating, breaking numbers into parts, or using shortcuts to quickly find answers. This skill relies on understanding numbers, patterns, and relationships, allowing you to solve addition, subtraction, multiplication, or division problems efficiently. Mental arithmetic helps improve number sense and problem-solving abilities, and is useful in everyday situations, such as shopping or managing finances, where quick, accurate calculations are needed without external aids.
