Units, Quantities And Estimation
Akopọ
A good answer is not just correct, it is sensible. Choosing the right units, working in consistent scales, and estimating before you calculate are the habits that separate a confident problem-solver from someone who trusts a calculator blindly. A quick estimate is your safety net against answers that are wildly too big or small.
In this lesson you will choose and use appropriate units and scales, convert between them, and round numbers to make fast estimates. You will then use those estimates to check the reasonableness of answers to multi-step problems, a skill examiners reward across every topic.
