Explanation:

To find the significant digits we have few methods.

METHOD 1--Count from left to right

A number that has a decimal point, count digits from the first number from the left that isn't zero.

METHOD 2--Count from right to left

A number that doesn't have a decimal point, count digits from the first number from the right that isn't zero.
