  2. Review: How many significant figures 804.05 0.014403 1002 400 30000. 0.000625000

  3. How can you write seven thousand with • 1 significant figure • 4 significant figures • 6 significant figures

  4. Round each to 3 Significant Figures • 31.068 6) 149.51 • 2.613 7) 6.561 • 81.436 8) 13.1252 • 0.001567 9) 143.81 • 1.1353 10) 0.000355

  5. Multiplying and Dividing • Multiply or divide the number out as normal but round the answer to the least number of significant figures in the problem

  6. Solve each with correct Sig Figs • 2.4 x 15.82 = • 94.20  3.16722 = • (5.682 x 105) x (2.87 x 104) = • (2.145 x 10-5)  (6.75 x 104) =

  7. Addition and Subtraction • Add or subtract as normal but round the answer with the same number of decimal places as the quantity in the calculation having the least

  8. Solve each with correct Sig Figs • 5.44 – 2.6103 • 2.099 + 0.05681 • 4.6521 + 183.2 + 240 • 0.004375 – 0.0036
