This model then is used to model metric distances in physical space-time and to explore the physical implications for the propagation of light. A nice feature of the model is that it provides a new conceptual framework for building a constant with dimensions of length into space-time.

Proceedings Royal Academy , 64 , The mean value of credit card accounts is dollars. A study was done of recent college graduates and found their mean value for their credit card accounts was dollars.
The number line below shows this situation. How far apart are these values? We subtract the two numbers and recall that when we subtract two negative numbers when we are looking at the right minus the left, we make them positive and subtract the positive numbers. In statistics, we are asked to find a z-score, which tells us how unusual an event is.
The first step in finding a z-score is to calculate the distance a value is from the mean. The number line below depicts the mean of Find the distance between these two points. To work out the calculation above on a number line, the smaller number is put at the start, with the larger number at the end. Then children can jump up in 10s until there is a number less than 10 left to add:. During Years 4 to 6, teachers will use number lines to demonstrate negative numbers, decimal numbers and fractions.
Here are some examples of how number lines will be used:. Learning Street will introduce number lines to the children slowly.
