The formula is automatically copied from the first cell to the rest of the cells in the range

Click your left mouse button to proceed . . .

Instead of summing Column A, you are summing Column B

You copied the function one column to the right

The new formula is adjusted one column to the right

This is called Relative Addressing

A’s become B’s

Click your left mouse button to proceed . . .

This is called Relative Addressing because the formulas are adjusted “relative” to how they were copied

Of Course, the Cells Show the Results of the Formulas
