Lesson details

Lesson outcome

I can appreciate the impact of rounding errors when using a calculator (or other technology), and the way that these can be compounded to result in large inaccuracies.

Show transcript
When given a rounded number you can say what the biggest and smallest values of the unrounded number could have been. When using technology for multi-step calculations you might round along the way. Rounding too early can cause answers to be incorrect Repeated rounding in multi-step calculations can lead to large errors.
