The equation given to me is: Log 1000000 = 6 Log 1000 = 3 Log 1.01 = 0.00432 I see how to do this. The issue is the following: I am told to put these values into the formula: \r

\n" );
document.write( "\n" );
document.write( "I cannot figure out how to enter the formulas or what keys to press to get the answer 694. I have tried everything without success. I think my biggest problem is not understanding what actual buttons to push or sequence of numbers to get to the answer 694. Also I think I am misunderstanding the minus sign in between the 6 and the 3. I have noticed the 6 is raised higher than the 3 in the original equation. Sincere Thanks, Ande Lu\r
