  1. 360 ÷ 12 xx 2 + [ ( 11 – 4 )^3 – 343 ] xx 2017^2018
    -> 360 ÷ 12 xx 2 + [ 7^3 – 343 ] xx 2017^2018
    -> 360 ÷ 12 xx 2 + [ 343 – 343 ] xx 2017^2018
    -> 360 ÷ 12 xx 2 + 0 xx 2017^2018
    -> 30 xx 2 + 0
    -> 60 + 0
    -> 60
     

  2.     360 : 12 × 2 + [( 11 – 4 )^3 – 343 ] × 2017^2018
    = 360 : 12 × 2 + ( 7^3 – 343 ) × 2017^2018
    = 360 : 12 × 2 + ( 343 – 343 ) × 2017^2018
    = 360 : 12 × 2 + 0 × 2017^2018
    = 360 : 12 × 2 + 0
    = 30 × 2
    = 60
