Mittag-Leffler summation is a way to find the sum of an infinite series. It helps us figure out what to do when we have a bunch of numbers that go on forever. It's like adding a bunch of numbers together, but instead of stopping at the last number, you add all of them together, even the ones that never end. To calculate the Mittag-Leffler summation, you start with the first number in the infinite series and add it to the second number. You keep on going, and add each number to the sum until you reach the infinite number. In the end, the summation will tell you the sum of the infinite series.
