ELI5: Why is something divided through zero not treated similar like an imaginary number? | g6qpnx | false | explainlikeimfive | Mathematics | So in grade 7 math we learned that you can't take the square root of negative numbers because any number squared is always going to be positive. A few years later we learn that you can actually calculate with the square root of negative numbers. You replace the square root from -1 with i. So why aren't we replacing something divided by zero also with a letter? |

eli5 number probability | t2jcmd | false | explainlikeimfive | Mathematics | I have a truly burning question. If you pick a number 1-10 100 times completely randomly and each number has a 10% chance of being picked each time (so picking a 7 once doesn’t decrease the likelihood of picking it on the next try) why won’t you end up with 10 of each number? |

ELI5 the concept and solution of Fermat's Last Theorem | g35bzg | false | explainlikeimfive | Mathematics | Mathematics has always fascinated me, but something I cannot wrap my head around is Fermat's Last Theorem, more specifically the solution to it (that Andrew Wiles found). I sort of get the basics of the Theorem itself, but for the love of God help understand it better. |

ELI5: Why can't dividing by 0 be done in a theoretical field? | 103lb03 | false | explainlikeimfive | Mathematics | As a layperson who is interested in math, imaginary numbers always fascinated me. Like in the real world you taking the square of a negative makes no sense whatso ever, but in theoretical math you can just invent new imaginary numbers, make it so that i ^2 = -1 and suddenly you have just revolutionized math. If this is useful, why can't you break other rules and account for them with new imaginary symbols? So let's pretend that we call them made up numbers and use m to represent them. Why is m =1/0 impossible when something like i ^2 = -1 is not? |
ELI5: the proof of the new result showing MIP* = RE | eqt5lh | false | explainlikeimfive | Mathematics | Here is the paper.

ELI5 Interpreting a 1.96 [1/exp[B] result of a neuropredictive study. I have absolutely no idea what the hell this means. | u2a2b9 | false | explainlikeimfive | Mathematics | The text: The ACC was the only unique significant predictor that was robust to bootstrap resampling. For every one unit in- crease in ACC activity, there was a 1.96 (i.e., 1/exp[B]) decrease in the probability of rearrest (P < 0.001).

ELI5: Why do we take the mean before the root in RMS (root-mean-square)? | idm4tv | false | explainlikeimfive | Mathematics | I searched on here and found some great explanations about why we square first : because if our data are centered about zero (or has any magnitudes that are different in sign), we are interested in the magnitudes rather than the average (which might be zero). However, once we've squared the data, we take its mean (to get the magnitudes squared on average) and then square root (to get the magnitudes squared). This is obviously different from taking the square root and then taking the mean (because we'd be dividing by N and not √(N) ), but why do we use the first method over the second? |
ELI5 How does a hash function work? | ie1m32 | false | explainlikeimfive | Mathematics | I understand that it’s purpose is that two similar inputs yield wildly different outputs, but how exactly do they work? Are there any simple hash functions? |
