#color(red)(=17)#

#[18/(9xx1)]+17-2#

#= [18/9+15]#

#= 2+15#

#color(red)(=17)#

~Hope this helps! :)

See a solution process below:

Using the PEDMAS method, first, execute the Multiplication operation within the inner Parenthesis:

#[18 -: (color(red)(9) * color(red)(1)] + 17 - 2 =>#

#[18 -: 9] + 17 - 2#

Next, execute the Division operation within the Brackets which is another form of Parenthesis:

#[color(red)(18) -: color(red)(9)] + 17 - 2 =>#

#2 + 17 - 2#

Now, execute the Addition and Subtraction operations from left to right:

#color(red)(2) + color(red)(17) - 2 =>#

#19 - 2 =>#

#17#
