Maths and Statistics
On your calculator you will often need to round up numbers with lots of decimal places to an appropriate level of accuracy.
In the video (below) Dee Greig-Dunn, Lecturer in Mathematics and Meteorology at Solent University, explains:
- how to round up to one, two and three decimal places
- how to round up to a specified number of significant figures
Remember: check the size of the next significant figure. If it's 5 or over, the number will round up. If it's less than 5, the number will stay exactly the same.
