Editor’s note: Dr. Tyler DeWitt has several videos on scientific notation and significant figures, and you might want to view all of them, as I have; see the first one here.
However, on this page I’d like to present the essence of these presentations; a formula to help negotiate scientific notation.
For common notation converted to scientific notation:
See the general rule at the top of the photo:
Start at the decimal point. This will have a value of 100.
If you move to the left, the exponent will go up;
if you move to the right, the exponent will go down.
For scientific notation converted to common notation:
See the general rule at the top of the photo:
Start at the decimal point. This will have a value of some exponential power.
If you move to the left, the exponent will go up to become 100.
if you move to the right, the exponent will go down to become 100.
Please be advised to see Dr. DeWitt's presentation here.
