When solving equations (of e.g. 2nd grade) the discriminant is part of a squareroot.
A square root of 'x' is the number that multiplied y itself equals 'x'.
Any number we can think of - when multiplied by itself (squared) gives a positive number. (even negative number - e.g. -2*-2 = 4)
So we cannot think of a number which square is negative.
Then sq.root(-1) has no answer - no number squared gives -1.
Therefore the number that equals sq.root(-1) is imaginary.

What are the rules of cubing for negative numbers?
the same as all integer exponents, repeated multiplication the indicated number of times. Negative numbers when cubed yield negative numbers.
What combination of signed numbers always leads to a positive number?
If I understand the question correctly, the sum of two positive numbers will *always* yield a positive number. The product of two positive or two negative numbers will always yield a positive number. The division of two positive or two negative numbers will always yield a positive number. There are more examples along this line. I am not sure if this is what you wanted to know.
Can you define percent yield in general terms?
% yield is the amount obtained from a reaction divided by the amount that can possibly be obtained times 100.% yield=(actual yield/theoretical yield) * 100%actual yield=the real amount of product that is actually produced in the reaction.theoretical yield=the imaginary amount of product that is likely to form.
How do you use positive number in a sentence?
A negative number multiplied by a negative number will yield a positive number.
What is the combination of real numbers in math?
It depends on the combination. Real numbers are closed with respect to arithmetical operations (+, -, *, /), as well as integer powers (exponents). So a combination of real numbers using any of these operators will yield a real number. But the set is not closed with respect to some fractional powers - for example, the square root of a negative number is not real.It depends on the combination.
