basic integer rules  can you tell me with numbers that have different signs in the same sign there's a Adderall to follow rules different when they're adding and subtracting multiplying dividing  you're adding a society and you have the same time both positives are both negatives you simply add your numbers and you keep the same sign that you're dealing with already  if they're different signs you find the difference of the two and take the sign the largest number I'll give an example of those in just one moment  when you're multiplying dividing rules are a little bit different if they're both the same you finally answer me so they're both positive your answers positive they're both negative Ranch will also be positive if you're different you simply multiply the numbers in your interest in egg now the show some examples of what I was talking about that's how you start off with the Positive $5 in your pocket you get to school and you want to buy something that cost $3 so you paid out or not all that person $3 to get the item  he's take a difference 2 by -3 is to it since your five is a large number and it's positive your answers also positive but you don't have to think of those rolls every single when does use common sense if you have $5 and you pay out three of course you're going to have $2 left over  now let's say for instance you have were you borrow $8 from a friend you get your allowance which was only $5 this week and you're able to pay him the 5 so you had both ate you now have 5 in your pocket you pay the spear friend at 3. That $5 you owe them you take the difference 8 minus 5 3 your side of your larger number is now a negative so now your answer is also negative but again using common sense if you owe 8:28 and all you're able to pay them is 5 of course you're going to owe them  $3 to remember positive means you have  negative uo  now let's look at multiplying and dividing there are two simple ways to remember that's if you have a hard time with the rolls rolls aren't that hard let's review them did the same sign a positive and a positive your answers positive if there's a same negative a negative your answer still positive same thing goes if they're different does it matter which order whether it's negative positive or positive negative your is there will be negative  one simple trick to remember there's some of you like us to take Tac Toe role does no problem with that you simply put the additions down the what do negatives along your edges can you follow your order if it's a positive and a negative you're a positive and a negative your answer is negative if you have a negative and a positive your answers negative to negative your interest positive to positive your answers causes you can even go down to negative positive negative positive negative support anyway you fall to take test of what will give you your answer  another way to number this using the same Tic Tac Toe board since it's already set up is to think about a good situation versus a bad situation if if you had a good person and something bad happens to him that's a bad thing if a bad thing happens to a good person a bad thing bad thing happens to a bad person that would be a good thing and if a good thing happens to a good person that's a good thing
