First you work out the brackets, then the multiplication, then do the addition/subtraction.

so, (8-2) = 6.
and 18 x 2 = 36

now, 36 + 6 - 15
= 42 - 15
= 27

18*2+(8-2)-15
=18*2+6-15 Step 1: Solve the term in brackets
=36+6-15 Step 2: do the multiple term
=27 Step 3: solve the problem

Reason.
Plus and minus seperate differant terms
Ex: 18*2 is term one
(8-2) term 2
15 is term 3
Always first solve the term.

18 x 2 + (8 - 2) - 15
u star multiplication first and the parentheses
= 36 + 6 -15

=42 - 15
and finish it with subtraction
=27

perform the operation on the inside of the parenthesis of the equation first and follow math rules which is to perform Multiplication followed by Division followed by Addition and then Subtraction. for you to remember the rules easily just say My Dear Aunt Sally which letters M stands for Multiplication, D for Division, A for Addition and S for Subtraction. Thru this you can solve any kind of arithmetic problems using these rules. For your question above, this is my solution.
