 Oct20 comment Couple Probability @BrianM.Scott welcome back from skullpatrol, now known as Ice Boy, and the rest of the gang in the chatroom :-) Sep26 comment How do you read the symbol “$\in$”? Would these two different roles of a variable be more clearly shown in the phrases: "any value of the variable in its domain" versus "the specific, but as of yet unknown, value of the variable"? Sep26 comment “Negative” versus “Minus” clap, clap, clap Sep19 comment How do you read the symbol “$\in$”? Thank you for the helpful links. Sep19 comment High school math definition of a variable: the first step from the concrete into the abstract… Thank you for your answer(s). How is this question related to your answer here? Sep18 comment How do you read the symbol “$\in$”? Ho Hey Jul25 comment How find this limit $I=\lim_{n\to\infty}n^a\left(\int_{0}^{\pi/2}\sin{(nx)}\cos^n{x}dx\right)=b$ Please come back @Chris'ssis Jul3 comment Trying to explain what “consistent” means to a middle schooler @DaveL.Renfro what would be the first math thing you would use? Jun29 comment Trying to explain what “consistent” means to a middle schooler Thank you for the clear explanation, but how can this be shown at the elementary Algebra level studied in middle school at the age of 13 years old? Jun26 comment Multivariable calculus - scalar field Before posting hints, maybe we should let the OP express his/her ideas :-) Jun26 comment Multivariable calculus - scalar field Do you have any ideas? May3 comment What is the difference between equation and formula? Note: Not every equation is a formula; but by the above definitions, every formula must be an equation in algebra. May3 comment What is the difference between equation and formula? Similar to the distance formula: $D=rt$ May3 comment What is the difference between equation and formula? I would say it is a fuel efficiency formula. May1 comment No difference between $0/0$ and $0^0$? May1 comment No difference between $0/0$ and $0^0$? Because it means division by zero. May1 comment No difference between $0/0$ and $0^0$? But the expression $0^0$ has no meaning. May1 comment No difference between $0/0$ and $0^0$? This is a nice summary of "What is $0^0$" May1 comment No difference between $0/0$ and $0^0$? When you say "strictly" speaking do you mean if using the standard algebraic definition of division as $a \div b = \frac{a}{b} = a*\frac{1}{b}; b\neq 0$?
