A measured quantity includes the digits that are certain and the first uncertain digits. Rules Governing Significant Figures : Rules Governing Significant Figures All non-zero digits are significant. : All non-zero digits are significant. Example: 1.234 kg. has four significant figures. Zeroes between two non-zero digits are significant. : Zeroes between two non-zero digits are significant. Example: 40.507 cm. has five significant figures. Zeroes to the left of the first non-zero digits are not significant. : Zeroes to the left of the first non-zero digits are not significant. Example: 0.009 has only one significant figure. If a number is greater than one all zeroes to the right of the decimal point are significant. : If a number is greater than one all zeroes to the right of the decimal point are significant. Example: 7.000 has four sf. 4005.0 has five sf. If a number is less than 1, only the zeroes at the end of the number and zeroes between two non-zero digits are significant. : If a number is less than 1, only the zeroes at the end of the number and zeroes between two non-zero digits are significant. Example: 0.02010 has four significant figures. The zeroes immediately to the left of an unexpressed decimal point are not significant. : The zeroes immediately to the left of an unexpressed decimal point are not significant. Example: 400 has one sf. Rounding-off numbers to Significant Figures : Rounding-off numbers to Significant Figures If the first non-significant digit is less than 5, then the least significant digit remains unchanged. : If the first non-significant digit is less than 5, then the least significant digit remains unchanged. If the first non-significant digit is greater than 5, the least significant digit is incremented by 1. : If the first non-significant digit is greater than 5, the least significant digit is incremented by 1. If the first non-significant digit is 5, the least significant digit can either be incremented or left unchanged : If the first non-significant digit is 5, the least significant digit can either be incremented or left unchanged All non-significant digits are removed. : All non-significant digits are removed. tAnx 4 Listening : tAnx 4 Listening Prepared by: Jhomar E.
