, Measured Numbers - answersNumbers you obtain when you measure a quantity using
a measuring tool.
Exact Numbers - answersAre those numbers obtained by counting items or using a
definition that compares two units in the same measuring system. (EX: 8 doughnuts; 1

A number is a Sig Fig if it is - answers1.Not a zero (4.5)
2.One or more zeros between nonzero digits (205)
3. One or more zeros at the end of a decimal number (50.0)
4. In the Coefficient of a number written in Scientific Notation
(5.70 x 10)
A number is NOT a Sig Fig if it is - answers1. At the beginning of a decimal (.00004)
2. Used as a place holder in a large number without a decimal point
(250000)
Rules for Rounding Off - answers1. If the first digit to be dropped is 4 or less, then it and
all following digits are simply dropped from the number.
2. If the first digit to be dropped is 5 or greater, then the last retained digit of the number
is increased by 1.
Multiplication and Division rules for Sig Figs - answersIn multiplication and division the
final is written so it has the same number of Sig Figs as the measurement with the
fewest Sig Figs.
Addition and Subtraction rules for Sig Figs - answersIn addition and subtraction the final
answer is written so that it has the same number of decimal places as the measurement
having the fewest decimal places.
