You can't. A number is not something you can change. A number just is.
Take a nice number like (-2). (-2) Is now, always has been, and always will be a negative number. You can use it in mathematical expressions like (-2)*(-3), (which evaluates to a positive number, by the way), but nothing you can ever do or say will change what (-2) means.

Will this entropy change by positive or negative?
If the system becomes more disordered, the entropy change will be positive. If the system becomes more ordered, the entropy change will be negative.
What kind of change can ions have?
positive or negative charge. A+
Does all matter have a negative or positive charge?
No, not all matter has a negative or positive charge. Matter can be neutral, meaning it has an equal number of positive and negative charges, such as in most atoms. Charged particles exist in matter, such as electrons with a negative charge and protons with a positive charge.
Will this entropy change by positive or negative n2 g 3h2 g 2nh3 g?
negative
Will this entropy change by positive or negative air is pumped into a tire?
entropy is decreasing, so negative
How do you change a negative number into a decimal?
You divide the negative number by a positive number for it to stay positive. And you divide the negative number by a negative number for it to become positive.
What does a positive number minus a positive numbe equal?
you change the minus to a positive and change the 2nd positive number to a negative number..the answer can be either negative or positive depending on the sign of the greatest number(:
What is a negative multiplied by a negative?
negative*negative=positive negative/positive=negative negative\negative=positve negative-positive=change the sign to a plus and then change the number after the sign and get your answer negative +positive=which ever numbr is bigger minus positive+positive=positive
Why the product of two negative numbers is positive.?
Multiplying something by a negative number makes it change signs. A positive number multiplied by a negative is negative therefore a negative * a negative is positive.
How do you determine negatives or positives in math equations?
Numbers are justified as positive, which is usually written as just a number but can be written with a plus (+) sign in front of the number. (e.g. 15 or +15), or negative. Negative numbers are numbers in the negative integers, or below 0. They are written with a minus (-) sign in front of them. (e.g. -15) ---------------------------------------------------------------------------------- ..::To solve remember these rules::.. When multiplying: positive x negative = negative positive x positive = positive negative x negative = positive When dividing: positive / negative = negative positive / positive = positive negative / negative = positive When adding: In a positive + negative situation, if the negative number has a higher number than the positive (e.g. -25 + 10) then the number is negative, this is always true when adding a higher negative to a positive. If the positive has a higher number (e.g. 25 + -10) then it's just the opposite, it will be a positive number. -------------You can solve these very easily: 25 + -10 --> (25) + (-10) to keep it well organized and easier to work with,now just remember "Keep Change Change"... - keep 25 as it is, change "+" to a "-" and change the "-10" to a positive 10. As a result, you will have: 25 - 10. Now solve. Answer = 15 (positive). If for instance you have a negative + positive, the same rules apply (Keep Change Change) negative + negative = negative positive + positive = positive When subtracting: negative - positive (vice versa), use Keep Change Change as you did with adding positives and negatives. negative - negative, use Keep Change Change positive - positive, use Keep Change Change if the number you are subtracting is a higher number. (e.g. 10-15) If you need anymore help, try asking a more specific question again on Wikianswers, search for math websites on the web, or ask your teacher or college professor for help.
When you subtract a negative number by a positive number is the number positive or negative?
5 - (-2) ______ 7 In this problem, it equals a positive because you do keep (5), change (- to +) change (- to + again). Keep, change, change. 6 - (-7) _____ 13 Again, we do keep (6), change (- to +), change (- to + again) So, positive.
What are the rules fr multiplication and divisions of integers?
(positive number) x (positive number) = positive number (positive number)/(positive number) = positive number (positive number) x ( negative number) = negative number (positive number)/( negative number) = negative number (negative number) x (negative number) = positive number (negative number)/(negative number) = positive number
If you change the number of electrons you get a positive negative or neautraul?
That depends on how you change the number of electrons.
What does a negative number multiplied by a negative number equal to?
A positive number. Positive Number x Positive Number = Positive Number Positive Number x Negative Number = Negative Number Negative Number x Negative Number = Positive Number
Does a positive number times a negative number equal a negative or a positive number?
A negative number. A positive number x a positive number = a positive number A negative number x a negative number = a positive number A positive number x a negative number = a negative Hope this helps :D
How do you work out how to times a positive number by a negative number?
A positive number times a positive number will always get you a positive number A negative number times a negative number will always get you a positive number (same signs will get you a positive number) but A positive number times a negative number will always get you a negative number or A negative number times a positive number will always get you a negative number (different signs will get you a negative number)
When you multiply a negative number by a positive number is the number positive or negative?
The result of multiplying a positive number by a negative number is a negative number.
