You can do operations on numbers like on a regular calculator.
    2.5 + 3 * 5 = 17.5

You can do operations between times and numbers.
    2 * 25 min = 50 min
    1 hr / 2 = 30 min

    8:25:13
    3.5 hr

You can convert times to another unit.
    2 hr 10 min 3 sec = 2.168 hr = 130.05 min = 7803 sec

You can do 'modulo day' to convert a time to a day time.
    6:00:00 PM + 14 hr = 32 hr
    32 hr  Modulo 24h = 8:00:00 AM

The calculator supports parentheses and the operator priority (multiplication and division have higher priority than addition and subtraction).
    (2 + 3) * (20 - 2 * 10) = 5 * 0 = 0
