A negative exponent of a number is the same as the reciprocal of that same number to the equivalent positive exponent.
EXAMPLE : 2-3 = 1/23
When multiplying powers of the same base the rule is, addthe exponents.
So, if the initial exponent is negative then the number has to be multiplied by a power of that number with an equivalent positive exponent greater than the negative exponent.
EXAMPLE : 2-3 x 25 = 2(-3+5) = 22 (As 5 > l3l then the resultant exponent is positive)
by doing reciprocal
If you have 10^-3 then you can consider it the same as (1/10^3) and you have changed the negative exponent to positive exponent. Similarly, if the original number is (1/10^-3), that is equivalent to 10^3. In most cases it is as simple as taking the reciprocal.
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
Change the number or variable with the exponent from the numerator to the denominator, or from the denominator to the numerator, and at the same time change the exponent from negative to positive. For example, 5-3 = 1/53, and 1/x-10 = x10.
a positive plus a negative is a positive example 9-(-2) you would change the double negative to a positive hope this helped :)
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.
Industrial Revolution has both the negative and positive changes in the history of Americans.
The negative sign will change to a positive sign when subtracting negative numbers from positive numbers so you will simply add them together.
Negative. Heat is lost.
left to right positive,right to left negative rate
a molecule having slightly negative and positive ends with regard to change
when you square a negative number you also get a positive result (because a negative times a negative gives a positive)
positive or negative charge. A+
