Significant digits are digits that provide useful information, for instance 123 has 3 significant digits and 30010 has 4 significant digits. So basically zeros aren't significant unless they are between two other numbers. 0.1020 has only 4 significant digits. A+: 4
0.00684 has three significant figures The product of 7.6 x 1.246321 has two significant figures. 28623 has five significant figures. 1.20000 x 10-19 has six significant figures. Trailing zeroes after a decimal point are considered significant. In scientific notation, only the numbers before the multiplication symbol are considered significant.
Used properly,they tell us how precise it is. The rule of thumb for significant figures is "every digit you're sure of, and one you're not". So if you're positive something is 123 and a bit, you could do 123.3 or 123.7 or whatever based on your best guess to the last digit.
Since the numbers begin with 123, they all contain a 3. As a result, they all "contain 3 or 7". So the remaining 4 digits can be any digits and this gives 104 = 10,000 such numbers.
