What if the 1.75 was negative? Would the addition between the two be changed to subtraction or would it remain
as -3.03i+ -1.75j ??

Do most teachers use calculators? Mine insists that you need to be able to do all the math in your head by giving us equations that we can feasibly do so with. However I'm worried that in real life the kind of equations I will be dealing with will be to complicated to do in my head.
