Simplify the Summation

Lesson Page 2, Section 6

What you'll work on

Read summation (∑) notation, identify the starting index, ending index, and rule, then evaluate each term and sum them to find the total.

Big Idea for this lesson

$A soft cream-white painted illustration of a single large flowing painted ribbon shape suggesting a folded scroll loop, with three small painted dots cascading downward below it like falling beads gathering at the bottom — ink-on-parchment with warm scholarly tones, no text or letters.$

A summation (∑) is structured repeated addition. The bottom of the sigma tells you where to start, the top tells you where to stop, and the formula tells you what to add each time. Evaluate each term, then add them all up.
