BODMAS is an acronym and it stands for Bracket, Of, Division, Multiplication, Addition and Subtraction.
This explains the order of operations to solve an expression. According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve/simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.
Example :
7 + (6 × 52 + 3) = 7 + (6 × 25 + 3)
7 + (150 + 3)
7 + (153)
7 + 153
Ans: 160.
