Summation is adding up of a sequence of numbers. Usually, the summation is given in this form ∑ni=1 aiwhen the terms in the sequence have a pattern and can be expressed using a general term.

Integration is basically the area bounded by the curve of the function, the axis and upper and lower limits. This area can be given as the sum of much smaller areas included in the bounded area.
