Mathematicians often wish to discuss mathematical objects, so in a mathematics text the subject of a sentence can be a mathematical symbol or formula. For instance, □ is a box symbol. “□” is a box symbol. x is a variable. ”x” is a variable. ”x = y” is an equation. are al...
(B1) The symbols for arithmetic operations +, −, ·, ×, ÷; root extraction 11√; differentiation d/dx, and the sum (union υ and the product (intersection) ∩ of sets. The symbols for the individual functions, such as sin, tan, and log, also fall into this category. ...
Others\int \oint \sum \prod Different classes of mathematical symbols are characterized by different formatting (for example, variables are italicized, butoperatorsare not) and differentspacing.

In code:std::iter::Sum::sum((0..n).map(|k| 2 * k + 1).into_iter()) // Out: 10000important: range in Rust has an inclusive lower bound and exclusive upper bound, meaning that ... (0..100) is equivalent to the sum of ... for k=0 to k=n....
For example, 5 ± 2 could in practice be any number from 3 to 7.∑ SumThe ∑ symbol means sum.∑ is the Greek capital sigma character. It is used commonly in algebraic functions, and you may also notice it in Excel - the AutoSum button has a sigma as its icon....
sum += 2 * i + 1; } // 10200 Sigma can also be nested, with the right-most sigma getting evaluated first unless the expression uses parentheses to alter the order. And in code: let sum = 0; for (let i = 1; i <= 2; i++) { for (let j = 4; j <= 6; j++) { sum...
