You must have learn BODMAS rule in alegbra,
ie. Order of operations
rders(ie Powers and roots)
Operator Precedence specifies how tightly
it binds two expressions together.
2 + 2 * 3 = 8, it is not 12 because multiplication (*) operator has a higher precedence than the addition (+) operator.
(2 + 2) * 3 = 12 , because now Brackets (Parentheses) are given more importance.
