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.

negatives and positives

All positives are greater than negatives. Because there is no minus sign on the 0.01 the 0.01 HAS to be bigger. Math is intresting, eh?

They are the same except equations use the equal sign =

Some include: Positives and Negatives Derivatives and Integrals Adding and Subtracting Multiplying and Dividing Reciprocals in fractions such as 1/2 and 2 (2/1) In a triangle there is the base and the adjacent leg to it.

IF they are math related, write appropriate equations and then apply math rules to solve the equations.

Equations mean a problem mostly in math

A short definition of engineering is "applied science". You need all sorts of equations in engineering: equations from pure math, from physics, chemistry, etc., depending on what you work in. I suppose any of these equations might be called a "math equation".

Multiplying or dividing a positive and negative gives a negative result. Multiplying or dividing two negatives gives a positive result.

Math equations have an equals sign such as: 7+5=12 or 9x6=47+7 Math expressions do not have a equals sign such as: 43-27 or 8x40
