It depends on the number of significant figures from two numbers you are multiplying. But when multiplying you use the same number of significant figures from the numbers you are multiplying with the LEAST number of significant figures. Example: 92,873.239 * 2 = 200,000 (because the number 2 has only 1 significant figure even tho 92,873.239 has 8 significant figures your answer still only has 1 significant figure)
