Terminology

What is a cell?

A cell is a single box in the spreadsheet grid where you enter data — a number, text, or a formula. Every cell has its own unique address.

How are cells named?

Each cell is named by its column letter + row number. The cell in column B, row 5 is B5. The top-left cell is always A1.

What is a range?

A range is a group of connected cells, written First:Last. A1:A5 is a column of 5 cells. B2:D4 is a rectangular block of 9.

Why cell references matter

Type =5+3 and you get 8 — forever. Type =A1+B1 and the answer stays live: change A1, and the result updates on its own.
