BODMAS Rule
This rule depicts the correct sequence in which the operations are to be performed, so as to find out the value of the given expression.
B - Bracket
O - Of
D - Division
M - Multiplication
A - Addition
S - Subtraction
Thus while simplifying an expression the operations must be executed according to this BODMAS rule.
Modulus of a Real Number
Modulus of a real number a is defined as
If a > 0 then |a| = a. If a < 0 then |a| = -a.
Hence, |7| = 7 and |-7| = -(-7) = 7.
Bar (or Virnaculum)
If an expression contains a bar over it then before applying the BODMAS Rule we simpify the expression under the bar.
