Negative - a positive would make it keep it change it change it so the problem would look like this -8 + -2 = -6, Im in honors math just to let you know, with all the subtraction problems, if they are integers,you do keep it change it change it keep the first digit and don't do anything to it change the subtraction sign to an addition sign and if the next integer is positive make it a negative if it is a negative make it a positive.

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.

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.

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

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.
