In mathematics, sub is often short for "subtraction." It refers to the operation of finding the difference between two numbers or quantities. Subtraction is usually denoted by the symbol "-". For example, if we have the equation 10 - 4, the sub operation would give us the result 6. This operation is the opposite of addition, where you bring two numbers together. Subtraction can be used in various mathematical contexts, such as solving equations, finding the difference between measurements, or calculating the change in a quantity. Understanding sub is vital for building a strong foundation in mathematics and helps in various problem-solving scenarios.
