ETERMINE # ,ADDITING & MULTIPLY SIG FIGS.docx Tools Help R Q Normal BI U A - A - 看員 三三 How many Significant digits are in the following? 1) 956044 2) 2.1390 3) 043900 4) 0.00500 5) 3500 7) 0.40001 6) 5.901 x 104 8) 1.0700 x 10-3 9) 7550. 10) 36070000 Round off the following numbers to three significant digits: 11. 120000 14. 4.53619 12. 5.457 15. 63.659 13. 0.0002739 16. 986493 Significant Digits (continued) Significant figures in derived quantities (Calculations) In all calculations, the answer must be governed by the least significant figure employed. ADDITION AND SUBTRACTION: The answer should be rounded off so as to contain the same number of decimal places as the number with the least number of decimal places. In other words, an answer can be only as accurate as the number with the least accuracy. Thus: 11.31 + 33.264 + 4.1 = 48.674 Rounded off to 48.7 MULTIPLICATION AND DIVISION: The answer should be rounded off to contain the same number of digits as found in the LEAST accurate of the values. Thus: 5.282 x 3.42 = 18.06444 Rounded off to 18.1
