In order to represent the square root of a minus number (which does not in fact actually exist other than as an abstract notion), mathematicians use an imaginary number called "i". i represents the value of the square root of -1. We must remember that it is not a real number, which is why we call it imaginary.
So to answer your question, i, or a multiple of i, times itself equals a minus number.
For example 2i * 2i = -4 (this is because we can rewrite -4 as 4 * -1. The square root of 4 is 2 and the square root of -1 is i. Therefore the square root of -4 is 2i).

What is the answer to 2 minus Ln times 3 minus x equal 0?
so, if 2 minus Ln times 3 minus x equals 0, then 2 minus Ln times 3 equals x, therefore 2 minus Ln equals x divided by three, so Ln + X/3 = 2 therefore, (Ln + [X/3]) = 1
What is an integer minus three times itself equals twenty six thirds?
That has no integer solution. Three times an integer is another integer; if you subtract to integers, you get an integer again, not a fraction.
