nested expressions. parenthesis, brackets, then curly brackets.?

Question

if have:
( { [ (2 + 5) * 4 ] / 3 } /5 )

can we start over again after the curly brackets Parenthesis then brackets then Curly Parenthesis and so on?
or there is another symbol after the curly brackets?

Answer 1

You would start again with normal parentheses. The innermost parentheses are separated from the other set by the square brackets, so ambiguity won't creep in.

Answer 2

( { [ (2 + 5) * 4 ] / 3 } /5 )



= ( { [ (7) * 4 ] / 3 } /5 )



= ( { [ 28 ] / 3 } /5 )



= ( { 28/3 } /5 )



= ( 28/15 ) ..................... answer

Answer 3

the version is via the fact in an equation you will possibly do brackets then parentheses. there's a distinction,by way of fact in case you probably did the parentheses first you will possibly finally end up with the incorrect answer.
