Dtruthspeaker: The point is that, the Hens is not the answer to the question the op is asking for. It is the produce (product). The eggs. That is what the concept is about. Multiplication is about product. Whether hens, oranges, money etc. What is the amount produced? |

BobFischer: 0*3 means zero in three places while 3*0 means 3 in zero places (no space for it to exist). |

Aucun:Your example is logical: 3×7 is the same as 7×3 i.e seven multiplied by three is exactly three multiplied by seven. But 7×0 and 0x7 which in mathematics yield the same result are illogical e.g 0 naira x 7 is still 0 naira, but 7 naira x 0 naira still leaves 7 naira intact, therefore the maths defies logic. |

Aucun: The issue is, the thinking level is too poor, that's why we are not productive in Africa. Our level of reasoning is so poor. The question isn't the issue but the reactions it generate, we are far behind here. |

Bolingua1: Can you please explain the concept of "BREAKING EVEN" in business. I am not an accountant, but Op is a thinking man. I would not say a genius, but he posed a thinking man's question. Many companies are happy to break even for years. Which practically means that they added 0 to the 1000 they invested, but they still have the 1000. Hence the question by Op. Why can't 1000 x 0 = 1000. |

BobFischer: The answer is SIMPLE if we understand the meaning of multiplication and the meaning of zero. Here is an example to explain it. "Zero" practically means "No" For instance, Zero sales = No sales Zero apple = No apple Zero space = No space Zero money = No money Zero bag = No bag Zero Shit = No shit Zero sense = No sense Etc In mathematics, "To Multiply" simply means: "Obtain from (a number) another number which contains the (first number) a specified number of times.... Eg, 10 x 0 = another number which is unknown to us Using the above definition which I modified from what I found in a Google search, The above equation can be interpreted as; Obtain from (ten) another number which contains (ten) (zero) times. If "zero" means "No", Then, let's do this: Obtain from (ten) another number which contains (ten) (No) times So, which number contains 10, zero number of times? Possible answers are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 If we choose any number greater than or less than zero, then we will continue to encounter problems whenever we try to reverse our process Therefore, the perfect answer is Zero Got this? Ok, let's solve a real life example using Oranges 10 oranges x 0 = ? Obtain from (ten oranges) another number of oranges which contains (ten oranges) (0) times So, which number of oranges contains 10 oranges, 0 number of times? 1 orange? 2 oranges?, 3, 4, 5, 6, 7, 8, 9 oranges? Nope! There's no number of such oranges except 0 oranges Therefore, the answer is 0 Now Do This 10 oranges x 7 = ? Obtain from (ten oranges) another number of oranges which contains (10 oranges) (7) times So, which number of oranges contains 10 oranges, 7 number of times? 20 oranges contains 10 oranges only 2 times 40 oranges contains 10 oranges only 4 times Therefore, the perfect answer is 70 oranges because it contains 10oranges 7 times. Ok, let's try this way; 10 x 1 = ? Obtain from (ten) another number which contains (ten) (one) times So, which number contains 10, one number of times? 10. Therefore, answer 10. Another example 10 x 100 = ? Obtain from (ten) another number which contains (ten) (100) times So, which number contains 10, 100 number of times? 1,000 Therefore, answer 1,000 If you are able to understand my explanation very well, then I'm sure you'll love to read my little book called The Untold Money Sense After all, why do we learn mathematics?

A real number multiplied by zero is zero. i.e X*0=0 Proof Assume the statement is false, i.e X multiplied by zero equals a non-zero real number Y. X*0=Y Divide both sides by X, you have Y/X=O This contradicts the closure property of the set of non-zero real numbers under multiplication and division because the set of non-zeros form a group under multiplication. Therefore, X*0=0. QED |

Re: Why Is Any Number Multiplied By Zero Equals To Zero? by YakubuA: 2:25pm On Jan 14, 2021 |
BobFischer: In my opinion the zero signify absence of the thing. So absence of anything x by any number = absence Hence I will rewrite your expressions as follows: 0 x 10 = 0 (0+0+0+0+0+0+0+0+0+0 = 0) 0 x 100 = 0 (0+0+0+0+0+0+0+0 upto 100 = 0) 0 x 1000 = 0 (0+0+0+0+0+0+0+0 upto 1000 = 0) Hence 0 orange x 100 = 0 orange 0 pear x 1000 = 0 pear The fact that you have 100 oranges confirm the presence of orange hence the number 1 (0 is absence and 1 is presence) So 1 orange (presence) x 100 = 100 oranges 1 pear (presence) x 1000 = 1000 pears So you can never have 100 oranges and multiply it by 0 but by 1 because you cannot have the oranges to be present and absent at the same time. Hope this help. |

Let me respond as a professional mathematician: First, you need to know that multiplication means repeated addition. What do I mean? 3 x 4 = 3 times 4 or 4 times 3 (commutativity property) = 3 + 3 + 3 + 3 (or 4 + 4 + 4 ) = 12 If you have 10 x 0, then it means zero is added in 10 places: 0+0+0+0+0+0+0+0+0+0 =0 By the commutative property, you could say 10 in no place at all I hope this helps. |

mu2sa2: It's simple. In plain English you can say 0*3 means you were given no apple three times (assuming the person sharing the apples did not give you any even though he shared 3 times) while 3*0 means that there was simply no time that 3 apples were given to you. |

I should start by acknowledging that these are proud NL days (better thread enter FP) gbayii! Too many ppl miss d point (which is subject) and until u recognize that u'll fink d question invalid. Ppl giving quotes like, "u can't give wat u don't av" are so wrong cuz (with regards to d matter) u can't give wat u don't av but if I av and I don't give, I should still av sebi? Mathematically, datz: 0 (give) X 3 (av) = 0 3 (av) X 0 (give) = I should Still av na abi? Lemme explain d matter again using the variables (cash n wallet) When the subject is cash, if I have 0 (cash) X 3 (wallet) , I still have no cash but When the subject is wallet, I have 3 (wallet) X 0 (cash) , shouldn't I still have 3 wallets? Well the solution is, multiplication deals in production. So using my examples, When d subject is wallet, I av 3 (wallets) X (I want to reproduce more wallets) 0 (cash) = I cannot reproduce any wallet. The perfect quote for this is , "it takes two to tangle". Hope I made sense. Yep 1 Like |

Bolingua1: What a pity!. You are now making it an African issue. This hypothesis was brought to us by the white man. The same way they told us that Jesus is a White man with long beard and that we all must accept and worship him. Op is just trying to question some the things we were thaught at British styled education. |

koning: Think of Product. If you have 100 cows, you have 100 cows. If they don't produce any milk, it is zero product. Zero milk. As you get that, you understand. If you have no money to share. Even if you have a good mind to share money to 10,000 people, you can only produce zero money. Multiplication is about finding the PRODUCT. |

100 + 0 = 100 You have added 0 (nothing) to 100, so you get 100 back. 100 * 0 = 0 You have multiplied nothing from 100 or produce nothing from 100, so your product is = 0 In simple English If you are asked what you have it is 100 If you are asked what you produced it is 0 Simple English, |

But if you come from a philosophical perspective, zero is ambiguous because it lacks definition. Zero represents nothings but there's no such thing as nothing. If you say there's nothing in your pocket, you are wrong because there's space, and oxygen in your pocket. You cannot say you are doing nothing. Infact it's impossible to do nothing because you're existing and existing is not nothing. That is part of the ambiguity of nothing of which zero inherits the same ambigius property. 1 Like |

mu2sa2: The order does not really matter. 0 is absent of a thing and 1 is present of a thing So absent x present = present x absent = absent Hence 0x3 = 3x0 = 0 1 Like |

koning: See, guy (or are u a lady?)! The concept of break even is different from what the OP is talking about. I'm an accountant. To break even means that, your revenue is the same as your expenses/costs. For instance, you spent 10k and make income of exact 10k... no profit, no loss! It's different from what the OP is talking about. Unless you have a variant point to make. |

Re: Why Is Any Number Multiplied By Zero Equals To Zero? by YakubuA: 2:43pm On Jan 14, 2021 |
mu2sa2: That is because the presence of the 3 apples changes the number from 0 to 1 (with 0 being absence of apple and 1 presence of apple). So when you have 3 apples ( presence) it can only be 1 apple present + 1 apple present + 1 apple present = 3 apples present = 3 apples x 1 present = 1 apple x 3 present = 3 apples |
