Question Type 3: Adding and subtracting complex numbers in Cartesian form Exercises

Calculate $(4+3i)+(5-6i)$.

Compute $(2-5i)+(-3+4i)$

Calculate $(2+3i)-(-1+2i)+(4-5i)$

Calculate $(5+2i)-(3+7i)$

Calculate $(1+2i)+(3 - i)+(-4+5i)$.

Compute $(7+3i)-(-2 - i)$

Calculate $(-3+7i)+(6+2i)+(0-4i)$

For complex numbers $z_1=a+bi$ and $z_2=c+di$, express $z_1 - z_2$ in the form $x+yi$.

For $z=5-3i$, calculate $2z-(z+4i)$
