I assume you're just clowning around here, as i think we both know it is ludicrous that a european from france or russia or wherever is lecturing a middle easterner on his arabic, LOL. Comparing the prophet to daesh are we now? I think we both know from the historical records that the prophets subjects were treated very well, orders of magnitudes better than under the other arabic states of the time, it was known that when the prophet took a city or a region or whatever, he didnt plunder it, kill the men, or sell the women and children into slavery. The conquest of mecca, no blood was shed, no prisoners, no destruction, no nothing, in stark opposition to Arab convention at the time, and indeed the romans and Persians as well. His treatment of the populations of conquered peoples far exceeded expectations, and anyways, why am i tiring myself typing this massive response debunking your false claim, how about you give me evidence to him treating women like daesh, one instance, just one, ill be content. If you want to say that islam is bad because of daesh, then christianity (what i assume you follow), is terrible, because of one crime that far exceeds any other act committed by the human race, the german attrocities of ww2, but i dont believe that, because the germans dont represent christianity and neither do daesh represent islam, and before you say, that daesh claims to be acting in the word of god, and so they represent the "wickedness" of Islam, the USA was built upon manifest destiny, which claimed legitimacy from the alignment of their wishes and god's desires, same with European colonisation. The thing is, i don't blame Christianity for the US's illegal settlement of native American lands or colonisation of Africa, so why do you blame islam for daesh? As for scientific miracles in the quran, both our holy scriptures share this, nothing new here, ill give you some examples to put your mind to rest once and for all(not a threat, lol): the detailed description of human embryos (quran:23:12-14), accurate claim that ants have the ability to communicate in ways far advanced in contrast to other creatures, and many more, but i think you get the point, No good morality? I think a 13th century jew living in the in baghdad would've laughed at the suggestion that the Islamic world had worse morality than, say, the Christian world (where would he rather live, baghdad or paris?). Once again, slavery in that part and time of the world was a part of the local economy, and banning it outright would've lead to economic collapse, and remember, slaves back then were treated much better than slaves in places like Europe or the USA were, back then slaves could rise to high positions of power, whether economic, military or political, just imagine that for a moment, from 19th century Europe, the treatment of slaves was MUCH worse than from 7th century Arabia. Now you might say that god could've came down with an economic system unreliant on slavery, and you'd be right, but by that logic, god could've done so many things, he could've lifted us all into paradise, he could've made a utopia for humans, he could've put a permanent stop to all wars forever, but that is not gods job, this life is meant as a test for us humans, to classify and separate the wicked and the good, to then introduce the real utopia to the doers of good. But what about Christianity? Slavery isn't banned in your religion either, what do you have to say about that? I interpret that hadith as metaphorical, so do many other groups and individuals alike, there is difference in opinion, however the underlying fact is that bukhari hadiths aren't as trustworthy as they seem, given by the fact that the hadith about aishas age contradicts both the quran, and historical records stating the age of aisha when she went on the hijra, and countless other of his "hadiths", and yes, god could've taught the arabs such medicine, but, once again, stop making me repeat myself, it was not his job to teach them medicine or what not (why bother anyway, the arabs would later invent all sorts of medicine in the islamic golden age 💪 ). Lies wont get you anywhere (: . I clearly told you about how if you make an incorrect prediction about your football or whatever, no one cares, this is different from pegging your entire religion to some outlandish prediction at the time, which, had it been disproven or otherwise, which would only happen after a few years from the prediction, would've shattered "his" religion and its validity. Clearly it is you who chose to ignore my response to your football predictions, a bit cheeky now isn't it (: . Now I don't know whether the big scary scholars you've been consulting with took their history classes in Chernobyl or not, but i can assure you that the prophet suffered far more than both john the baptist and jesus, with respect. like seriously, have you ever read a book? With all respect to you, but this claim is simply untrue, i want to give you a point to prove it, but a quick google search can show the sufferage of the prophet, and save me time explaining history to you. That aside however, i did not say that whoever suffered the most is ultimately correct, for an individual preacher to experience 13 years of torture and persecution, is not like for a government to send all its soldiers into the jungles of Vietnam to defend their country, having been forcefully drafted, the two have simply nothing in common, sorry to break it to you. What i did say however, is that the fact that he went through so much torment and suffrage, is proof enough that he wasn't in it for the moolah( or fame or worship or personal benefit or whatever). When you say religious minorities do better in the west, i assume you mean they are better of financially and economically, which, your right, im not here to argue my country is richer than france or norway lol, if you mean better of in the sense there rights are protected better, no, the treatment is the same. The reason my people come to your country is beacause they are in search of jobs and economic prosperity, not fleeing a mass ethnic cleansing, of course. And once again, telling me the jews suffered under germany alone negates the crimes committed by the west, is a laughable argument at best, all nations of the west have committed atrocities, the USA manifest destiny, and europe colonisation and conquest. I am talking about islam and the periods closest to the prophet here, not modern governments, if you are suggesting than in the 12th century jews were treated better in the west than in the middle east, i really dont know if there is any hope left for you. (Jews were persecuted all across europe, fun fact). but before that time, islamic civilisation was the absolute top dog in contrast to the west, i think this is indisputable

To find the number of trailing zeros in the factorial of 2017 ( 2017 ! 2017!), we need to determine the number of times 10 (which is composed of the prime factors 2 and 5) divides into the factorial. The number of trailing zeros is determined by the minimum of the powers of 2 and 5 in the prime factorization of the factorial. First, let's find the number of times 5 divides into the factorial: ⌊2017/5⌋ + ⌊2017/25⌋ + ⌊2017/125⌋ + … = 403 + 80 + 16 + ... =403+80+16+… Now, let's find the number of times 2 divides into the factorial: ⌊2017/2⌋ + ⌊2017/4⌋ + ⌊2017/8⌋ + = 1008 + 504 + 252 + … =1008+504+252+… Since the number of 2s will be more abundant than the number of 5s, we only need to consider the count of 5s.(ignore the 2s) therefore the solution is: ⌊2017/(5*2)⌋ + ⌊2017/(25*4)⌋ + ⌊2017/(125*9)⌋ + … = (ignore the 2s) ⌊2017/5⌋ + ⌊2017/25⌋ + ⌊2017/125⌋ + ... = 403 + 80 + 16 + ... =403+80+16+… Adding up the counts, we get: 403 + 80 + 16 + 3 = 502 BTW this is jc maths it is normal if we dont undertand

Using a displacement can, you can work that out experimentally first like the story of archimedes and the king’s crown. This gives you a hypothesis that you can then prove using various methods.
