What are two types of spreadsheet addressing?

The two types of spreadsheet addressing are relative and absolute addressing. Relative addressing adjusts the cell reference when a formula is copied to another location, while absolute addressing maintains a fixed reference to a specific cell, regardless of where the formula is moved. Absolute references are indicated by dollar signs (e.g., $A$1), whereas relative references do not use dollar signs (e.g., A1). These addressing types help users manage data calculations effectively in spreadsheets.
