Understanding  Absolute  and  Mixed  Cell  Referencing  

•  Absolute  cell  referencing  – To  indicate  that  a  cell  reference  (both  column  and  row)  –  or  even  a  part  of  a  cell  reference  –  should  remain  unchanged  when  copying  

– Syntax  =  $  before  column  le[er,  before  reference  number,  or  both  

•  Mixed  cell  referencing  – A  cell  reference  that  has  only  one  $  – Common  when  you  need  to  copy  a  formula  both  down  a  column  and  across  a  row  at  the  same  Gme
