WebSolution: We use the rules of addition and subtraction to write each expression in the form x + i y. ( 2 + 3 i) + ( 1 + i) = ( 2 + 1) + ( 3 + 1) i = 3 + 4 i. 1 − ( 2 + i) = ( 1 − 2) + ( 0 − 1) i = − 1 − i. Addition of complex numbers can be thought of as addition of the corresponding vectors in R 2.

WebIn our algebra and calculus classes, where we worked in Q and R, all non-zero numbers had multiplicative inverses. For example, 5 − 1 = 1 5 since 5 − 1 ⋅ 5 = 1. But 1 5 ∉ Z! 🔗. When we're working with only integers, in particular in congruence classes modulo an integer m, fractions aren't a thing. Some numbers, though, do have ...
