Adding and Subtracting Complex Numbers

z_{1} = a_{1} + i b_{1}; a_{1}, b_{1} \in ℝ, i = \sqrt{- 1}

z_{2} = a_{2} + i b_{2}; a_{2}, b_{2} \in ℝ, i = \sqrt{- 1}

Adding Complex Numbers

z_{1} + z_{2} = (a_{1} + a_{2}) + i \cdot (b_{1} + b_{2})

Subtracting Complex Numbers

z_{1} - z_{2} = (a_{1} - a_{2}) + i \cdot (b_{1} - b_{2})
