Significant Figures

Significant figures act as a form of honesty in scientific reporting. They implicitly guarantee that a value is known to a certain degree

We measure how many positions of a number we know for certain!!

Significant Figures

100 - less precision, we only know 1 position for certain

100.001 - more precise, we know 6 positions for certain

Significant Figures

Example:

100 --> less precise, I know for certain 1 number

100.010 --> a more precise value, I know for certain 6 numbers

100 = 1

2200 = 2
