Which addition does the model below represent? +
+
+
O 8+(-3)
O2+(-3)
O 5+ 3
O +
5+(-3)

I am suggesting the answer is the last one 5+(-3)

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
