When we are working with the operations of complex numbers we will defer to using sum and difference rules. Sums include the use of the addition rule, additive identity, and additive inverse. In any of those cases, the first thing you should do is combine all the like terms that you see. When trying to assess differences it gets a little easier, you just need to use the subtraction rule. The goal with this set of worksheets is to correctly add and subtract complex numbers by applying the proper formula in order to balance the given equations.
These worksheets and lessons will help your students to understand the concept of complex numbers and absolute values by practicing addition and subtraction problems involving equations of this type.
