What adds to 5 minus negative 2 gives you the result 6?

-1

You apparently want to find the value of x such that ...

... x + 5 -(-2) = 6 . . . . . . the problem statement

... x + 5 + 2 = 6 . . . . . . . simplify signs

... x +7 = 6 . . . . . . . . . . . perform the addition

... x = 6 -7 = -1 . . . . . . . subtract 7 from both sides of the equation, evaluate

-1 adds to 5 - (-2) to give the result 6.

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.
