How do you prevent a negative sign appearing when you have multiplied a percentage by a total?
If the percentage and the total are both positive numbers, then there's no reason for the appearance of a negative sign.
What if you have a negative plus a positive number?
Negatives and subtraction go hand - in - hand For Example, - 5 + 3 = - 2 could be also seen like this. 3 - 5 = = -2 Your answer will be negative if the number with the negative sign is bigger than the number with the positive term. If both numbers are negative then you add them up as normal numbers like positive and just put a negative before the total. - 5 - 5 = - 10 - 5 + (- 5) = -10
What is the sum of first 10 positive numbers?
The first ten positive numbers total 55.
What are the rules for adding and subtracting negative and positive numbers?
Addition and Subtraction of Positive and Negative numbers is very simple once you grasp the knowledge of how to do it. Simply remember when a + and a - are together you - the values and when the signs are the same you + the values. -+ = - +- = - ++ = + -- = + Examples: [1] 10 + -9 = 10 (+-) 9 = 10 - 9 = 1 [2] 10 - +9 = 10 (-+) 9 = 10 - 9 = 1 [3] 10 + +9 = 10 (++) 9 = 10 + 9 = 19 [4] 10 - - 9 = 10 (--) 9 = 10 - 9 = 1 Note : The above is much too complex for younger student minds. FIRST Rule : Gather together all the numbers with the same signs. Then add all the positive numbers together. Do the same for the negatives. Finally, subtract the negative total from the positive total, to get the final combined total or answer.
How many eight digit numbers are there?
There are 90,000,000 whole numbers.If you include negative numbers, this doubles to 180,000,000.If you include decimal numbers, eg 1.2345678, there are 666,000,000 positive numbers, disallowing numbers with extraneous 0's.Including negative numbers, this doubles to 1,332,000,000If you allow trailing 0's in the decimal place, than this becomes 730,000,000 non-negative numbers, or 1,459,999,999 numbers (since -0.0000000 = 0.0000000)If you allow a decimal point without a digit in front, there are a further 90,000,000 non-negative numbers, or 180,000,000 including negative numbers.Allowing trailing 0's, this becomes 100,000,000 non-negative or 199,999,999 numbers.Maximum total:1,659,999,998 allowing trailing 0's, and allowing numbers without a digit in front of the decimal point.

What do you call a balance of a negative and positive charges?
A balance of negative and positive charges is called neutrality. This occurs when the total negative charge is equal to the total positive charge, resulting in a system that is electrically neutral.
What is the sum of the oxidation numbers in a neutral compound equal to?
The sum of the oxidation numbers in a neutral compound is equal to zero. This is because in a neutral compound, the total positive oxidation numbers are balanced by the total negative oxidation numbers to give a net charge of zero.
How can you find the total value of a combination of negative and positive integers?
Combine them together, using the rules of priority (PEMDAS or BIDMAS).
What is the sum of first 10 positive numbers?
The first ten positive numbers total 55.
What is the sum of the oxidation number in a compound?
The sum of the oxidation numbers in a compound is zero for a neutral compound. This is because the total positive oxidation numbers from the cations must equal the total negative oxidation numbers from the anions to balance out and form a neutral compound.
How can one determine the net charge of an object or particle?
The net charge of an object or particle can be determined by adding up the positive and negative charges present on the object or particle. If the total positive charges are greater than the total negative charges, the object or particle has a positive net charge. If the total negative charges are greater, it has a negative net charge. If the positive and negative charges are equal, the object or particle has a neutral net charge.
What is total positive charges and negative are equal?
When the total positive charges are equal to the total negative charges in an atom or a molecule, the overall charge is neutral. This means that the number of protons (positive charges) is equal to the number of electrons (negative charges), resulting in a balanced electrical charge.
How can an object have a neutral charge if part of the object has a positive and a negative charge?
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.

How can ionic compounds be neutral if they consist of positive and negative ions?
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.
