Question

If u = 1 + 3i and v = -2 − i, what is u + v?

Answer 1

u = 1 + 3i

v = -2 - i

u + v = (1 + -2) + (3i + -i) = -1 + 2i

Answer 2

The sum of  u + v such that u = 1 + 3i and v = -2 − i  will be -1 + 2i.

What is a complex number?

A complex number is the combination of real and imaginary numbers.

the formation of a complex number looks like a + ib where part a is called real and part ib is called imaginary.

What is summation?

A summation, which is the result of adding two or more numbers or quantities, is also known as a sum.

A summation always has an integer number of terms. There might simply be two terms, but there might also be 100,000 or a million. Summations exist with an infinite set of elements.

Given that two number u = 1 + 3i and v = -2 − i

u + v = (1 + 3i) + ( -2 -i) = -1 + 2i hence it will be the correct answer.
