Hi -- it's not a bug it's a feature. Your equation is simplifyed after You enter it. That is nessesary because any expression must be ordered to make simplifications like 2*x*8 to 16*x the ordering is verry important to make the algebric rules work for the expressions. So it is not a good idea to switch it of. During this ordering of Your input x/x is canceled to 1 before Solve[] see the result. btw -- I hope You enter Solve[x/x+x==1,x] (double equal) Hope that helps Jens > Hi, > > I'm 16 and I can't understand how I (why me?) found this bug in > mathematica.
