12:25 Why did we change the negative 15 to a positive 15?..what I did was 3(-15)+10 -45+10 =-35

[@Greenemath]

It's inside of an absolute value operation. Those vertical bars around the -15 are telling you to take the absolute value: |-15|. The problem is 3 x | - 15| + 10 = 3 x 15 + 10 = 45 + 10 = 55. The absolute value operation makes things non-negative. So a negative 15 becomes a positive 15.

[@aprilalino2482]

so when you add a positive number to a negative, it subtracts? and if u do it the other way around it adds? I'm still kind of confused.

[@Greenemath]

You should first watch the videos on adding integers and subtracting integers. adding integers: kzbin.info/www/bejne/bH-0iZWqmLyhqrs subtracting integers: kzbin.info/www/bejne/pXvIg2usnrSWqa8 Long story short if you don't want to watch the videos. Adding Two Integers with a Common Sign: Basically the sign stays the same and you just add the absolute values. -5 + (-7) = -12 -2 + (-3) = -5 Adding Two Integers with a Different Sign: Think about both numbers in terms of absolute values. Basically just make the numbers positive. Subtract the smaller away from the larger. This gives you your answer in terms of absolute value. Use the sign of the original number with the larger absolute value. -17 + 11 Since -17 has a larger absolute value, the answer will be negative. So now all I have to do is subtract 17 - 11 = 6 -17 + 11 = -6 14 + (-8) Since 14 has a larger absolute value, the answer will be positive. So now all I have to do is subtract 14 - 8 = 6 14 + (-8) = 6 Hope this helps, if it doesn't drop the specific examples from your homework and I'll help you solve them.

I still get mixed up with when you have to turn adding to subtracting (or the other way around) like -2 + 6 do I add or subtract? I’ve been studying for 2 hours and I feel like still haven’t learned anything :(

[@Greenemath]

Unfortunately, it just takes a lot of practice. If you are working with integers, I would always add. So this means for a subtraction problem, you would do addition of the opposite. -2 + 6 = 4 because you would subtract 6 - 2 = 4 and keep the sign from the number with the larger absolute value. I would suggest watching videos on just adding integers and subtracting integers. When you feel comfortable, then move back into the order of operations. Adding Integers: kzbin.info/www/bejne/bH-0iZWqmLyhqrs Subtracting Integers: kzbin.info/www/bejne/pXvIg2usnrSWqa8 Here's a little practice test for you: www.greenemath.com/Prealgebra/19/AddingIntegersPracticeTest.html

[@sirmeowthelibrarycat]

🤔 Hello. There is another method to help you understand this problem. Draw a number line with zero at the mid point. Negative numbers appear on one side, positive numbers on the other side. Either direction is valid. -10. -9. -8. -7. -6. -5. -4. -3. -2. -1. 0. +1. +2. +3. +4. +5. +6. +7. +8. +9. +10 Now find -2. Then move in the positive direction 6 steps. You arrive at +4. That is your answer. I hope this is helpful for you.

[@sarasantos8593]

(2:49) I’m confused doesn’t a positive and a negative= Negative? Why is it positive?

[@Greenemath]

You are thinking of the rules for multiplication and division with integers. If the signs are different, your answer is negative and if the signs are the same, your answer is positive. With addition of integers, we have to think about which sign carries more weight. In this case we have 12 + (-9). If we think about these two numbers without the signs, one is 12 and one is 9, the 12 is larger, so this will carry more weight. This means we will have a positive answer. Another way to think about this is with a bank account. Suppose we have $12 in our account and we subtract away 9. We still have $3 dollars left, which is a positive amount.

[@kaeyynn]

I get it, but not with fractions. I’m such a slow person. Idk if I’m dyslexic or that I’m just dumb in reality, but I’m currently an 8th grader who can’t seem to understand the order of operations along with fractions. My math tutor doesn’t just directly give you the problem. They make you narrow it down many times. They do things like: (+3)x-8-(+3/8x1 1/2 + (+4/9)= and weird stuff like that , all those math symbols gets my mind confused and then I feel like giving up.

[@Greenemath]

Most people don't get math right away, so don't feel bad. The best thing to do is lots of practice. It's just like anything else, if you practice, you will get better over time. :)

[@hyelee6147]

im so sorry but im just pretty slow .. i just dnt get it this kind of problem .. (6 - (-3)) = 9 ??? why ?? i thought 3 is the answer .. can u pls xplain more ?? thank you

[@Greenemath]

When you subtract away a negative number, it is the same as adding a positive. So 6 - (-3) can be thought of as 6 + 3 = 9. Just change the subtraction sign to addition, then change the number being subtracted away to its opposite or you could say just change the sign. So for 5 - (-2) we change the minus to plus and change (-2) to (+2). We can write the problem as 5 + 2 = 7. Hope this helps some, integers can be challenging at first, but once you practice enough it will become second nature :)

[@hyelee6147]

GreeneMath.com so u mean sir/ma'am when two negative sign combine will it be positive ?? in any mathematical problem ?? for ex. -10 ÷ -5 = 2 or -2 ?? im so sorry im just pretty slow 😥

[@Greenemath]

The rules will differ based on your scenario. If you are dividing or multiplying, two negatives will give you a positive. In general with multiplication or division, the same sign will give you a positive result.

[@julioestorga9546]

Don't say that. Just go to the material repeatedly. Sleep with it wake up with it read it continuously do it. It will sink in your head. You will see the patterns nice and slow do not get frustrated. You're not a slow learner you're just not getting it. You have to really soak it up pay attention. Turn off the cell phone go to the library put earphones on really pay attention to it

[@tannerstockton8207]

Think. Six minus a negative number. You are subtracting 6 and -3, so the simplified form would be 6 + 3 = 9.

[@abdimohamed9669]

I didn't get the absolute value part, why did -15 become positive 15?

[@Greenemath]

The absolute value operation gives you a non-negative result. So if the number is negative, it makes it positive.

[@joannasmith9833]

Absolute value is always positive because it refers to the distance of the number from zero on the number line. "How many spaces from zero is -15?" Distance isn't negative.

Sorry to hear that, was there a problem that you are stuck on? I can walk you through it step by step if you like?

[@Codenamenarc007]

yeah i dont understand how to figure when im supposed to add the equasion or multiply etc like this 4-3x(3-_2)) is that a minus subraction symboy or a neggitaive @@Greenemath

[@Greenemath]

@@Codenamenarc007 The easiest way to think about this is by changing the subtraction to addition of the opposite. Now, the way your wrote the problem is a bit strange. There's an underscore in front of the 2? I'm going to modify your problem slightly: 4 - 3x(3x - 2) So what I would do is write the "-3x" part as + (-3x): 4 + (-3x)(3x - 2) You can also write the (-2) as + (-2): 4 + (-3x)(3x + (-2)) This seems like a lot of work, but if you are struggling with signs, it can help. Eventually, you will get comfortable and you won't have to do this. Now you can use the distributive property and distribute the (-3x) to each term inside of the parentheses. 4 + (-3x)(3x) + (-3x)(-2) 4 + (-9x^2) + (6x) -9x^2 + 6x + 4 So to keep things simple for you, I would change your subtraction to addition of the opposite. This will help you keep your signs straight. If you want to retype that problem, I can go through it. I don't know what the underscore 2 was?

First question was wrong the first step is actually negative 4

[@Greenemath]

The solution for the first question is correct: (-2)^2 = (-2)(-2) = +4

(5)(-6)+18-(15/-5)??????

[@Greenemath]

Let's just rewrite this for clarity: 5 x (-6) + 18 - [15 / (-5)] Let's start with the parentheses or in this case the brackets: [15 / -5] = -3 Now we will replace this in our problem: 5 x (-6) + 18 - (-3) = 5 x (-6) + 18 + 3 Nex, we will perform our multiplication: 5 x (-6) = -30 No we will replace this in our problem: -30 + 18 + 3 Now, we can just add: -30 + 18 + 3 = -12 + 3 = -9 5 x (-6) + 18 - [15 / (-5)] = -9

Thanks

umm i learned B E D M A S not pendas

[@Greenemath]

There are different ways to remember it. Most people learn PEMDAS. You just need to understand the correct order, however you decide to remember the order of operations. Good luck with your studies :)

You need some practice. www.greenemath.com/Prealgebra/23/PEMDASPracticeTest.html www.greenemath.com/Prealgebra/23/PEMDASTest.html

I have me -37

[@Greenemath]

If you have a question, I'm happy to try and help. I don't know what "I have me -37" means?

[@JanaMohamed-ul8uy]

Hi

[@Greenemath]

Perfect, thanks for watching :)

[@drbhavukgarg]

BODMAS

[@Greenemath]

That's another good way to remember it, it's the same as PEMDAS.

[@nadinepurdis3212]

You lost me at the -5. When you explained that -3 -2 was -3- +2. My thought would be to subtract because + and - = - and subtract the difference but you added instead and added a bonus of a negative. This part here Is where I would go wrong on a test.

[@Greenemath]

You can really think about subtracting away a number by adding the opposite of the number. So -3 - 2 = -3 + (-2). Now you can just follow the rules for adding integers with like signs. Since both are negative, just add the absolute values (ignore the signs) and then attach the negative. So we end up with -3 + (-2) = -(3 + 2) = -5. Hope this helps you :)
