\mymulticolumn{1}{x{5.377cm}}{To determine the number of significant figures in a number use the following 3 rules: \newline % Row Count 2 (+ 2)
1.Non-zero digits are always significant \newline % Row Count 3 (+ 1)
2.Any zeros between two significant digits are significant \newline % Row Count 5 (+ 2)
3.A final zero or trailing zeros in the decimal portion ONLY are significant \newline % Row Count 7 (+ 2)
Example: .500 or .632000 the zeros are significant \newline % Row Count 9 (+ 2)
.006 or .000968 the zeros are NOT significant \newline % Row Count 10 (+ 1)
For addition and subtraction use the following rules: \newline % Row Count 12 (+ 2)
1.Count the number of significant figures in the decimal portion ONLY of each number in the problem \newline % Row Count 15 (+ 3)
2.Add or subtract in the normal fashion \newline % Row Count 16 (+ 1)
3.Your final answer may have no more significant figures to the right of the decimal than the LEAST number of significant figures in any number in the problem. \newline % Row Count 20 (+ 4)
For multiplication and division use the following rule: \newline % Row Count 22 (+ 2)
1.The LEAST number of significant figures in any number of the problem determines the number of significant figures in the answer. (You are now looking at the entire number, not just the decimal portion) \newline % Row Count 27 (+ 5)
This means you have to be able to recognize significant figures in order to use this rule \newline % Row Count 29 (+ 2)
Example: 5.26 has 3 significant figures \newline % Row Count 30 (+ 1)
