Re: hey

64-59.62x92 = 64-5485.04 (multiply before subtract) = -5421.04

As a decimal fraction this is:

           4
-5421  ----
          100

Multiplying by 111987 keeping as decimal fraction is:

-5421 * 111987 - (4/100) * 111987

= - 607081527 - 447948/100 =  - 607081527 - 4479 - 48/100 = - 607086006  48/100

(Is this really a problem given to you?)

Re: hey

Sorry there, kiana, but "111987" looked like someone just jabbed the 1 a few times and then ran their fingers over a few more keys. Such an odd number.
