Bell Work 6 / Sig Fig’s Perform the following mathematical operation and use correct sig fig’s. 1. 43.39 + 4.098 = 2. 234.34 – 23.543 – 6.9 = 3. 0.09 + 7.9 + 123.0 = 4. 2.3 x 103 – 4.567 x 102 = Perform the following calculations using correct sig fig’s. 1. (6.022 x 1023 ) x (1.05 x 102) = 2. 3.78 (2.34 + 45.9) = 3. 9.0 + 4.5 + 2.45 - 0.98 = 4. (456.9 ÷ 34.5) – 3.564 =
