<p>Should I use a+bi mode all the time? I dont think there really is a difference from using real mode except that I could solve complex numbers. Does anyone know if it is bad to leave my ti84 on a+bi mode? Barrons said that I should use a+bi mode exclusively. What does that mean? Does that mean I should only use it on questions involving complex numbers? I left it on that mode while taking all my practice tests and I dont think it affected my calculations.</p>
<p>a+bi mode is perfectly fine</p>
