Subtract the two complex numbers 41+71i-61+27i

Please Help Me

Combine all the real number parts and combine all the imaginary number parts.  This is like combining like terms.

Juan,
 
You need to include parenthesis when you upload these questions.  I assume you mean
 
(41 + 71i) - (61 + 27i) = (41 - 61) + (71 - 27)i = -20 + 44i

Otherwise:  41+71i-61+27i 
                = 41 - 61 + 71i + 27i
                = -20 + 98i

Arturo, you accidentally transposed 7 in place of 71:
(41 + 71i) - (61 + 27i)
= (41-61) + (71- 27)i
= -20 + 44i
