How to Round with whole numbers
Do we always need to know the exact number? If you read in the newspaper 40,000 people watched the football game in the stadium, do you think exactly 40,000 people saw the game? Do you want to know the exact number of people? On many occasions numbers are rounded and being able to round properly will also be important on you IGCSE and GCSE maths exam. I encourage you therefore to look at the following maths videos properly during your maths revision and to try to solve all the example questions.
