(5+4)+1=( + ) write the numbers that make this equation true

(5+5)

Step-by-step explanation:

(5+4)+1=(+)

Ok so first of all, 5 plus 4 is 9. Add 1 to that is 10.

So you can easily say 9+1.

Or, 5+5.

There are so many choices for you.

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.
