True.
But it cannot be "fales", anyway since they is no such word ;D
Adding a negative amount is equivalent to subtracting a positive amount.
You will end up with a positive number. With integers, if you multiply or divide an even amount of negative numbers, the answer will be positive and if you multiply or divide an odd amount, the answer will be negative.
No
If the amount of negative integers being multiplied is even, the result will be positive. If it is odd (like 101), the product will be negative.
positive, it increases the amount of oxygen in the air.
If you have MORE positive amounts, than you have negative amounts, then the balance is a POSITIVE result. So answer is POSITIVE. Think of it like this:- -6+9 is the same thing as +9-6, and, 9minus 6 = 3 but we only bother with the 'sign' if the amount is a negative amount, so 3 always means +3
Take the positive one and subtract the negative amount.
equal but opposite
Neutral
If an object has both positive and negative charges in different regions, it can still have an overall neutral charge if the total amount of positive charge is equal to the total amount of negative charge. This results in a cancellation of the charges, making the object neutral overall.
Electrically neutral
The net charge of an object with equal amounts of positive and negative charges is zero. Positive and negative charges cancel each other out, resulting in no overall charge on the object.
