António Manuel Martins claims (@44:41 of his lecture quot;Fonseca on Signs quot;) that the origin of what is now called the correspondence theory of truth, Veritas est adæquatio rei et intellectus
- Difference between PEMDAS and BODMAS. - Mathematics Stack Exchange
Division is the inverse operation of multiplication, and subtraction is the inverse of addition Because of that, multiplication and division are actually one step done together from left to right; the same goes for addition and subtraction Therefore, PEMDAS and BODMAS are the same thing To see why the difference in the order of the letters in PEMDAS and BODMAS doesn't matter, consider the
- Proof of $7^n-2^n$ is divisible by 5 for each integer $n \ge 1$ by . . .

- Why is $\infty\times 0$ indeterminate? - Mathematics Stack Exchange
"Infinity times zero" or "zero times infinity" is a "battle of two giants" Zero is so small that it makes everyone vanish, but infinite is so huge that it makes everyone infinite after multiplication In particular, infinity is the same thing as "1 over 0", so "zero times infinity" is the same thing as "zero over zero", which is an indeterminate form Your title says something else than
- What are the criteria for bad faith questions?
There are two general types of questions, based on the assumed relationship between the question-asker and the question-answerer: Proper (knowledge-seeking) questions where the question-asker wishes to learn something that the question-answerer (ostensibly) knows Rhetorical (knowledge-testing) questions where the question-asker wishes to test or instruct the question-answerer on something that
- Prove that $1^3 + 2^3 + . . . + n^3 = (1+ 2 + . . . + n)^2$
HINT: You want that last expression to turn out to be $\big (1+2+\ldots+k+ (k+1)\big)^2$, so you want $ (k+1)^3$ to be equal to the difference $$\big (1+2+\ldots+k+ (k+1)\big)^2- (1+2+\ldots+k)^2\; $$ That’s a difference of two squares, so you can factor it as $$ (k+1)\Big (2 (1+2+\ldots+k)+ (k+1)\Big)\; \tag {1}$$ To show that $ (1)$ is just a fancy way of writing $ (k+1)^3$, you need to
