It is best to start practicing this with number lines. Start with positive number. if its a negative number, you go backwards.
If you have to combine, it is deemed addition. so lets say our positive is +7 and our negative is -9, the sum is +7+-9
The + and - may get confusing together. if you have ++ or -- together, this means +, and if you have +- or -+ together, these mean -.
So +7+-9 becomes +7-9, which counting back 9 (6,5,4,3,2,1,0,-1,-2) = -2
Combine them together, using the rules of priority (PEMDAS or BIDMAS).
The positive integers up to 4 are: 1, 2, 3, and 4. This is a total of four positive integers.
Aleph-null (a listable infinity).

Ionic compounds are neutral because, even though they consist of positive and negative ions, the relative proportions between those ions are such that the total number of negative charges is the same as the total number of positive charges, thus summing to zero.
If the percentage and the total are both positive numbers, then there's no reason for the appearance of a negative sign.
You mean, what happens when positive and negative charges are equal? That is simple, the equal opposite cancel each other out and we have an electrical neutrality
The sum of the first three even positive integers is 2 + 4 + 6 = 12.
I believe the answer your looking for in an Ion.An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
The total positive charge of an ionic compound equally balances the total negative charge; therefore, the ionic compound is electrically neutral.
