This Video Covers BODMAS For Waec, Jamb and other Exams. BODMAS Stands for Bracket, Off/Order, Division, Multiplication, Addition and Subtraction.
The Common Mathematical Operations are Addition (+), Subtraction (), Multiplication (x) and Division. 
Most Mathematics Questions in Waec, Neco, Jamb and Other Examinations Asking you to Evaluate or Simplify require the Use of BODMAS.
When Addition or Subtraction is Mixed with Multiplication or Division in any Question, we apply BODMAS to solve it.
