- 17 + [ 2 - { ( -8 ) + 3 - ( 9 x 7 - 13 x 3 ) } ]

let's do this according to BODMAS RULE

→ - 17 + [ 2 - { ( -8 ) + 3 - ( 63 - 39 ) } ]

→ - 17 + [ 2 - { ( -8 ) + 3 - ( 24 ) } ]

→ - 17 + [ 2 - { -8 + 3 - 24 } ]

→ - 17 + [ 2 - { - 29 } ]

→ - 17 + [ 2 + 29 ]

→ - 17 + 31

→ 14

• BODMAS is a short form for Brackets, Of, Division, Multiplication, Addition and Subtraction.
• According to Bodmas rule, if an expression contains brackets ( ( ) , { } , [ ] ) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.
• Solving the problem in the wrong order will result in a wrong answer.
