这就是数学书定义写完之后先给你来俩example的意义——显示存在性。唯一性有的话可以证但不一定有。
The index number is usually expressed in terms of i = number. The index number references the starting value, while the top number indicates the ending value. This means that all of the numbers inclusive of and between these two values are added together. For example, the follow summation ...

“They say, ‘Are you sigma Mr. Lindsay?’ or ‘Yo, that’s so sigma’ when I do something that pleases them like (assigning) math problems (to solve) with an online game,” he says, adding that in his classroom, “Sigma is going strong.”...
For example, 1 + 8 + 27 + ... + 1000 can be written using sigma notation as ∑10i=1∑i=110 i3, as the elements are the cubes of natural numbers from 1 to 10. How Do You Find Sigma in Math? To find the sigma in math, we either expand it and find the sum manually or we...
