Today in class, we learned about how to determine Significant Figures. First of all, I learned how to know which is significant figures by looking at the zeros that between the nonzero digits, for examples: 4005 – has 4 significant figures, or also 500.89 has 5 significant figures. Also, zeros at the end of each numbers which is to the right of a decimal point are significant. Example: 470.00 has 5 significant figures, or 20.02 has 4 significant figures. And for Rounding measurements, example: 264.832 => 2.648 x 10^2. And the rules of addition, substraction, multiplying and dividing.
