Can we override operators in Ruby? -


in case...such as

(10 + 20) * 10 => 300

the expression fragment enclosed in parentheses evaluated before higher precedence multiplication.so applies other operators well.can override other operators such << !...etc

when humans evaluate expressions, starting @ left of expression , working towards right. example, working left right result of 300 following expression: 

10 + 20 * 10 = 300

this because we, humans, add 10 20, resulting in 30 , multiply 10 arrive @ 300. ask ruby perform same calculation , different answer: 

> 10 + 20 * 10 => 210

this direct result of operator precedence. ruby has set of rules tell in order operators should evaluated in expression. clearly, ruby considers multiplication operator (*) of higher precedence addition (+) operator.

overriding operator precedence

the precedence built ruby can overridden surrounding lower priority section of expression parentheses. example: 

> (10 + 20) * 10 => 300

in above example, expression fragment enclosed in parentheses evaluated before higher precedence multiplication.

i hope makes clear understand :)
