The first rule says that all non-zero digits are significant. For example, in the number 345, all three digits are significant. The second rule states that zeros placed between non-zero digits are also significant. For example, in 1005, the zeros are significant because they are between numbers. The third rule explains that leading zeros are not significant. For example, in 0.0045, the zeros before 45 are not counted as significant figures. They only help to show the position of the decimal.
