Simplify the expression. (3-i)-(2+6i)?
I need help simplifying the expression (3 - i) - (2 + 6i). I understand that the answer is 1 - 7i, but I often get lost in the process. Could someone explain the steps involved in reaching that solution?

lol its not invisible numbers: imaginary numbers;
i is the same thing as sqrt(-1) which obviously is not a real number; thats why its imaginary. Sometimes, its easiest just to think of the i as an x. like you do with normal algebraic equations, combine like terms (3-2) and (i-6i) which gives 1 – 7i.
hope that helped!
