All nonzero digits are significant.
Zeros that appear between other
nonzero digits are always significant.
Zeros that appear in front of all of the
nonzero digits are called left-end zeros.
Left-end zeros are never significant.
Zeros that appear after all nonzero
digits are called right-end zeros.
Right-end zeros in a number that locks
a decimal point are not significant.

☐☐
Right-end zeros in a number with a
decimal point are significant.
This is true whether the zeros occur
before or ofter the decimal point.
237 has three significant figures.
1.897 has four significant figures.
39,004 has five significant figures.
5.02 has three significant figures.
0.008 has one significant figure.
0.000416 has three significant figures.
140 has two significant figures.
75,210 has four significant figures.
620.0 has four significant figures.
19.000 has five significant figures.
For multiplication and division problems, the answer should be
rounded to the same number of significant figures as the
measurement with the least number of significant figures.
