👉 Rounding is a mathematical concept that involves making an approximation of a number by estimating its value based on other values in the same set. It is used when we need to reduce the precision of a result and keep the accuracy within a certain limit. For example, if you are dealing with measurements like temperature or weight, rounding can be useful because it allows us to approximate the true value without changing the meaning of the measurement. For instance, instead of measuring 100 degrees Celsius, we could
