How do you treat each zero you come across?

Once you understand how to treat each ZERO you come across and relate it to where it is compared to the NON-ZEROs then it is time to combine all of your knowledge. Remember, make sure you understand the previous sections of significant figures before you attempt this one. To recap all the rules you have been taught.

ZEROS to the LEFT of NON-ZERO numbers are NEVER significant.

ZEROs BETWEEN NON-ZERO numbers are ALWAYS significant.

If your number DOES NOT show a decimal dot then all the ZEROs to the right of NON-ZERO numbers are NOT significant.

If your number DOES show a decimal dot then all the ZEROs to the right of to the right of NON-ZERO numbers ARE significant.
