- Learning Goal 1
- Comparison of numbers of very different size can be made approximately by expressing them as nearest powers of ten.

- Learning Goal 2
- Numbers can be written with bases other than ten. The simplest base, 2, uses just two symbols (1 and 0, or on and off).

- Learning Goal 3
- When calculations are made with measurements, a small error in the measurements may lead to a large error in the results.

- Learning Goal 4
- The effects of uncertainties in measurements on a computed result can be estimated.
