Semi Selection
A process of selecting a cell or range of cells for entering cell references as you create formulas That’s when you make a formula and lets say you choose A1 then you add it to C2 by clicking on it and the moving bars appear Relative Cell ReferernceA relative location, such as two rows up and one column to the left Example you copy original formula =D2-E2 from cell F2 down to F3, the copied formula changes to =D3-E3 JUST THE ROW NUMBERS CHANGE

Absolute Cell reference
Provides a permanent reference to a specific cell
$B$4= absolute cell reference pg 403
Example: Cell E 2 contains = d2*$B$4… WHEN THE FORMULA IS COPIED in cell E 3 = D3* $B$4 Mixed Cell Reference
Combines an absolute with a relative cell reference
When yo copy a mixed reference formula, either the column latter or the row number that has absolute reference remains fixed while the other part changes. Example: $B4 AND B$4
$B4—COLUMN B is absolute…. Column b does not change but the row number does change B$4--- B CHANGES, but row # 4 does not
