Answer 2

To calculate the expression you provided:

45 + 6.9 - 90 + 20 - 2.8 + 66 * 51 - 8.5 - 1181 / 9.732 / 4 - 649 / 7.88 + 9 + 87 + 3 + 76.9 + 612.0 / 40.9316 / 2 / 1

First, let's simplify the expression step by step:

45 + 6.9 - 90 = -38.1 -38.1 + 20 - 2.8 = -21.9 -21.9 + 66 * 51 = 3354.9 3354.9 - 8.5 = 3346.4 3346.4 - 1181 / 9.732 = 3233.5366629 3233.5366629 / 4 = 808.384165725 808.384165725 - 649 / 7.88 = 735.780090508 735.780090508 + 9 + 87 + 3 + 76.9 = 911.680090508 911.680090508 + 612.0 / 40.9316 = 925.362823848 925.362823848 / 2 = 462.681411924 462.681411924 / 1 = 462.681411924

Therefore, the result of the expression is 462.681411924.
