True. A complex number can be expressed in the form \( a + bi \), where \( a \) is the real part, \( b \) is the imaginary part, and \( i \) is the imaginary unit (defined as \( i = \sqrt{-1} \)). Thus, writing each complex number as a real number plus/minus an imaginary number is correct.
You should write each complex number as a real number plus/minus an imaginary number. * 2 points true false
