Answer:
C) 18
Step-by-step explanation:
To solve this expression, you follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction). In this case, you perform multiplication before addition and subtraction:
20 - 3 * 2 + 4
= 20 - 6 + 4 (Multiplication first)
= 20 - 6 + 4 (Subtraction next)
= 14 + 4 (Subtraction result)
= 18 (Addition)
So, the solution is 18.
