• Imformation
- / = divide
- neg = negative
- pos = positive

If anyone has questions about how you do this just remember...

-negative divided by negative = a positive
-neg/neg = pos
(-14/-2 = 7)

-negative divided by positive = a negative
-neg/pos = neg
(-20/5 = -4)

-positive divided by negative = a negative
-pos/neg = neg
(25/-5 = -5)

And of course...
-positive divided by positive = a positive
-pos/pos = pos
(108/12 = 9)
• are those lines bullet points, or negative signs?
probably bullet points right?
• is dividing positive and negative numbers like multiplying them?
• The rules are very much the same, if that's what you're asking. Like a negative divided by a negative will always be positive.
• if 5/0 is undefined,
and 0/0 is undefined,
how is 0/5 = 0?
0 has no value right?
So how can you divide a NON value thing by a number?
• If you were solving 8 / 2, you would find the number that you can multiply by 2 to create the 8. The answer is 4 because 2*4 = 8.

Now, follow the same approach with 0 / 5. Find the number that you can mulitply with 5 to create 0. The answer is 0 because 5*0 = 0.

Hope this helps.
• In He said "A negative divided by a negative is a positive"
That's the only part i don't understand.
• since there are 2 negatives, they cancel each other out. So you get a positive. :)
• Chuck Norris can divide by 0.
• If you divide by zero you will always get zero as the answer.
That's a fraction, by the way.
Simplify, I need help with s I m p l I f y .
• I guess you mean
846𝑤⁵𝑥𝑦³∕(765𝑥²𝑦⁴)

This can be written as
846∕765⋅𝑤⁵⋅𝑥∕𝑥²⋅𝑦³∕𝑦⁴

– – –

Now we simplify the rational expressions (fractions) one by one:

846∕765 = 2⋅3⋅3⋅47∕(3⋅3⋅5⋅17) [prime factorization]
= 2⋅47∕(5⋅17) = 94∕85

𝑥∕𝑥² = 1∕𝑥

𝑦³∕𝑦⁴ = 1∕𝑦

– – –

So, 846𝑤⁵𝑥𝑦³∕(765𝑥²𝑦⁴) = 94∕85⋅𝑤⁵⋅1∕𝑥⋅1∕𝑦
= 94𝑤⁵∕(85𝑥𝑦)
• if you ask siri 0/0 she will say that "it's the same as cookie monster having no cookies and you having no friends" which is kinda funny
• Dude Siri is like the best. I asked her if she loved me and she was like, Why wouldn't I? You use me way too much ;-3

• how do you divide a positive fraction by a negative fraction?
• I think that 1/2 divided by -1/4=-2
