Estimating & Rounding
MNU 301a
To run the tutorials simply click on the video you wish to play remembering to pause the video when attempting the questions! You should work through the exercises and homework in a squared jotter to keep all your work together. You should mark every section as soon as you finish it and write down your score.
For certain areas you will need a scientific calculator like the casio fx-85GT PLUS.
Once you have practiced the skills, be sure to see if you can apply them in the Applications questions at the bottom of the page. These questions should be revisited every so often as it is important to revise previous work so you don't forget it. Good luck! :)
