Division optional ; Raising to the powers of constant integers optional.
We can also write that number in scientific notation: What does that number actually mean? Can you actually imagine 4.
Graphical representation Although many topics in geoscience use scientific notation, graphical representations are often plotted on logarithmic scales as in the electromagnetic spectrum below. Log scale of electromagnetic spectrum. Details There are many reasons for this - most importantly, it takes up less space - but a log scale does not give a sense of true scale: Bar illustrating true scale of powers of ten.
Details Geologic time is a great context in which to talk about big numbers and to give a sense of scale. We have the geologic time scale to give students a sense of what parts of "time" we know the most about. And how big "time" really is. Here is a geologic time scale that gives a sense of scale Geologic time scale.

Calculators can be set up to display scientific notation. Spreadsheet programs can tabulate data, expressing it in a number of forms.
Scientific notation provides an excellent way for students to become familiar with their probably new calculators.Standard form in elementary-level mathematics is the number written in standard numerical form, such as 5, According to initiativeblog.com from the Oswego City School District, elementary mathematics usually lists around three ways to write numbers: standard, expanded and word name.
For example, the number 4, is already written in standard form. NOTE - The FARSite is the authoritative source for the AFFARS only.

If a watch says it's water resistant let’s say up to 50 meters, that does not mean that you can swim as deep as 50 meters below the surface, as long as you want and as often as you want, and experience no problems with the watch.
