1. all non-zero numbers are significant numbers
2. a zero which is located between two non-zero numbers including a significant number
3. all zeros located in the final row written behind the decimal point include important numbers
4. zero as a decimal point is not an important number
We must be able to distinguish between the significant number and the exact number. The significance number is obtained from the measurement results while the exact number comes from the numerical activity
