Negative numbers to even powers will be positive, negative numbers to odd powers will be negative. The answer is -16,384.

the answer of negative 4 minus positive 21 is positive 25 because you leave the negative 4 as is, change the minus to a plus, and change positive 21 to negative 21. (Leave Change Change)

Industrial Revolution had both negative and positive change in the Americans.

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

negative

a positive plus a negative is a positive example 9-(-2) you would change the double negative to a positive hope this helped :)

No. Negative numbers to even powers are positive.

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.

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.

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.

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(:

It truly depends on what the problem is, but normally a negative will change the overall answer of the sum: + and - = negative answer - and - = positive answer + and + = positive answer - and + = negative answer

Is called AC voltage or current.

10, 100, 1000, 10000, ... are the positive powers. 0.1, 0.01, 0.001, ... are negative powers.

Industrial Revolution has both the negative and positive changes in the history of Americans.

A negative powers is defined as the reciprocal of the corresponding positive power. For example, 10-3 is the same a 1 / 103.

The negative sign will change to a positive sign when subtracting negative numbers from positive numbers so you will simply add them together.

A negative divided by a positive is negative. A negative divided by a negative is positive. A positive divided by a positive is positive. A positive divided by a negative is negative.

Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative

Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative

a negative x a negative= a positive, a positive x a positive= a positive, a negative x a positive= a negative, and a positive x a negative= a negative. Same thing with division. a negative divided by a negative= a positive, a positive divided by a positive= a positive, a negative divided by a positive= a negative, and a positive divided by a negative is a negative. U see?

Negative. Heat is lost.
