11(3)(1)(5)-2(1)(5)+4(3)
Multiply 3 by 1 to get 3.
11(3)(5)-2(1)(5)+4(3)
Multiply 3 by 5 to get 15.
11(15)-2(1)(5)+4(3)
Multiply 11 by each term inside the parentheses.
165-2(1)(5)+4(3)
Multiply 1 by 5 to get 5.
165-2(5)+4(3)
Multiply -2 by each term inside the parentheses.
165-10+4(3)
Multiply 4 by each term inside the parentheses.
165-10+12
Subtract 10 from 165 to get 155.
155+12
Add 12 to 155 to get 167.
167
