- when a negative divides a negative, is the answer negative or positive?(56 votes)
- positive because negative times a negative is = positive and negative divided by a negative = positive(33 votes)
- I really need to engage in class more(17 votes)
- Don't worry you'll surely make it.(1 vote)
- what is 0 divided by 0?(8 votes)
- Good question! Note that 0/0 is the answer to the question “what number times 0 is 0?” Any number times 0 is always 0, so 0/0 can be anything! For this reason, 0/0 is called indeterminate.
If you take calculus later on, you will encounter 0/0 frequently when solving limit problems. This means that the result is inconclusive, so more work is required to calculate the value of the limit or determine that the limit doesn’t exist.
Have a blessed, wonderful day!(17 votes)
- if it's is easy then ask your teacher to get in a higher grade level math(15 votes)
- If you multiply a negative,a positive and a zero is it going to be zero still?(6 votes)
- Yes. Any value times 0 will equal 0.
This is the multiplication property of 0.(14 votes)
- Why is solving a problem with multiplying easyer than dividing? Its even more hard when they want to throw some fractions and letters into the problem.(8 votes)
- You see, some people was taught multiplication first, so that's why its easier than division, because its like the same thing but back wards. Vice Versa with division. Or maybe your brain works differently. And that nothing to be ashamed of!(6 votes)
- This is basically the same as multiplication. Two same signs equal a positive. Two different signs equal a negative. signs are these (-) (+) or (negative) (positive)(9 votes)
- thank you for Math(7 votes)
- why cant 0 be dived by 0 wouldnt be 0?(4 votes)
- We don't have a specific answer for that yet. It would be invalid to guess a number, because it could be anything. Any number times zero is zero, but zero first divided or multiplied is not yet figured out. That is because zero is not really a number. If you ha√e zero of something, that really just means you have none. Zero is neither a positive or a negative. But if you wanted me to answer, I would agree, because you have none. You add or subtract or multiply or divide none, it's still none. All you did was do more "none" things to it. So I would think that 0+0=0 0-0=0 0x0=0 0/0=0. Have a wonderful day! I hope my answer satisfied you!(1 vote)
