In mathematics, summation is the addition of a sequence of numbers, called addends or summands; the result is their sum or total. Beside numbers, other types of values can be summed as well: functions , vectors , matrices , polynomials and, in general, elements of any type of mathematical objects on which an operation denoted "+" is defined.
Sumowanie – operacja dodawania ciągu liczb, której wynikiem jest suma. Jeśli liczby są dodawane kolejno od lewej do prawej, to pośrednie wyniki nazywa się sumami częściowymi lub cząstkowymi. Sumowane liczby (zwane składnikami) mogą być całkowite, rzeczywiste lub zespolone.
3 paź 2022 · The symbol \(\Sigma\) is the capital Greek letter sigma and is shorthand for ‘sum’. The lower and upper limits of the summation tells us which term to start with and which term to end with, respectively. For example, using the sequence \(a_{n} = 2n-1\) for \(n \geq 1\), we can write the sum \(a_{3} +a_{4} + a_{5} + a_{6}\) as
Symbol sigma (Σ) Jeżeli dodajemy do siebie wiele składników i zauważamy pewną regułę, możemy do oznaczenia sumy stosować znak sigma (Σ). Zamiast pisać 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 możemy napisać: \(\displaystyle\sum_{i=1}^9 i\).
In general, we define the sum as: \ [ \sum_ {i=a}^b f (i) = f (a) + f (a+1) + f (a+2) + \cdots + f (b-1) + f (b).\] The symbol `\sum` indicates summation and is used as a shorthand notation for the sum of terms that follow a pattern.
