Best Answer

All digits between the first non-zero digit and the last non-zero digits are significant. Some would argue that trailing 0s are significant since they are an indication of the precision of the number.

A.when its between two digitsB.When it is right to the right of the decimal and it follows a non-zero digit.

If I understand this convoluted sentence correctly, then think it is true.

I'll assume you're asking about zeros. Zeros appearing anywhere between two non-zero digits are significant. In the other two cases they could be, but are not necessarily significant.

It is not a question of invention. The procedure follows from the fact that a decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right.

That is correct.

Zero is considered a significant digit when it is to the left or the right of the decimal point. It is also a significant digit when it follows a non-zero digit or when it is between two digits.

A significant figure is the number of digits to the left of the decimal place from the right most non zero digit to the left most digit, or the number of digits from the right most digit to the right of the decimal place to the left most digit. So, 5748 to two significant digits is 5700
