What is the definition of estimation?

Estimation refers to making a rough calculation of a value rather than obtaining an exact measurement or quantity. This approach is particularly useful when an approximate answer is sufficient for practical purposes, allowing individuals to make quick assessments without needing detailed information or precise calculations. Estimation helps in everyday scenarios, such as budgeting and determining time or resources required for a task, enabling individuals to make decisions based on reasonable approximations.

While options like precise calculation, rounding numbers, or analyzing percentages involve more exact and systematic mathematical processes, they do not encompass the broader and more informal nature of estimation. Estimation allows for flexibility in situations where exact figures may not be readily available or necessary, reinforcing its relevance in both everyday life and mathematical problem-solving.
