    So you can just divide 0 by t and it gets rid of it in the first step?

    @Venomblast let me tell you... if you divide any number by zero then it will result infinity like 1/0 ... but if you divide 0 by any number you'll get zero as answer... @Topkart33 yes t is divided by zero which results in zero...

    actually. 1/0 = undefine and 0/1 = 0
