BODMAS Rule

According to BODMAS you must do brackets first, then division, then multiplication, then addition and subtraction. When doing addition and subtraction, it is best to go left to right.

BODMAS is a common type of rule used in simplification. It means things like add, subtract, multiply, divide, squaring etc.

Here,

• BO refers to Bracket Open
  {(3x4)} + {(5x7)}
  3 x 4 + 5 x 7
  
  
• D denotes Divide
  \(\frac{45}{-5}\)
  Divide the absolute values
  \(\frac{45}{-5}\) = -9
  The signs are opposite = -9
  Thus, \(\frac{45}{-5}\) = -9
  
  
• M refers to Multiply
  15 x 4
  Multiply the absolute values
  15 x 4 =6
  
  
• A refers to Addition
  -5 + 15
  Add the absolute values
  -5 + 15 = 10
  The sign is positive because we have to put the greater one.
  
  
• S denotes Subtract
  8 -3
  Subtract the absolute values
  8 - 3 = 5
  The sign is of positive.
