start at the first non zero and count on

atlantic (absent)

start at the fist non zero and count on

addition/subtraction

line up the decimal points and cut off waht behind it to the right.

multiplication / division

count the original numbers and how many sig figs they have, then mult or divide as normal, then make the awenser have the same number of sig figs as the least one from the original numbers.

hypothesis

explains an observation

theory

scientific principle USED AS A MODEL to explain the results of testing a hypothesis.
