The formulas used so far have been relative references, meaning that they change when they are copied and pasted
When copying and pasting: • If we want to refer to the same cell all the time we use $ signs before both row and column $A$1 • If we want only the column to always stay the same we use a $ sign before the column letter $A1 • If we want only the row to always stay the same we use a $ sign before the row number A$1
