Powers of Ten
9 The Mathematical World
For Grades: 9-12
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.
