    3² * (5 - 7) - 55 + 65 - 6⁵ * 6 / 5 + 88 - 69 * 77⁵

    First, we simplify what's in parenthesis.  There is only one set so we do that subtraction:

    3² * (-2) - 55 + 65 - 6⁵ * 6 / 5 + 88 - 69 * 77⁵

    Next, we resolve any exponents.  We have two values to the fifth power and one value to the second power:

    9 * (-2) - 55 + 65 - 7776 * 6 / 5 + 88 - 69 * 2706784157

    Next we do any multiplications and divisions in order from left to right:

    -18 - 55 + 65 - 7776 * 6 / 5 + 88 - 69 * 2706784157

    -18 - 55 + 65 - 46656 / 5 + 88 - 69 * 2706784157

    -18 - 55 + 65 - 9331.2 + 88 - 69 * 2706784157

    -18 - 55 + 65 - 9331.2 + 88 - 186768106833

    Finally, add and subtract in order from left to right:

    -73 + 65 - 9331.2 + 88 - 186768106833

    -8 - 9331.2 + 88 - 186768106833

    -9339.2 + 88 - 186768106833

    -9251.2 - 186768106833

    -186,768,116,084.2

    3^2 * (5 - 7) - 55 + 65 - 6^5 *6/5 + 88 - 69 *77^5

    = -18 - 55 + 65 + 88 - (6^6/5 + 69*77^5)

    = 80 - 933840580821/5

    = -933840580421/5

    = -186768116084 1/5
