If x is a sign of multiplication, then 3-3x6+2 = -13 is incorrect.
The order of mathematical operation is PEMDAS.
1st operation to perform is the numbers inside a PARENTHESIS
2nd operation to perform is the number with EXPONENTS
3rd operation to perform is MULTIPLICATION
4th operation to perform is DIVISION
5th operation to perform is ADDITION
6th operation to perform is SUBTRACTION.
3-3x6+2 = -13
operation present are multipication, addition, and subtraction.
3-3x6+2 = -13
first, do multiplication : 3 - 18 + 2 = -13
second, do addition: 3 - 20 = -13
third, do subtraction: -17 = -13 ANSWERS ARE NOT EQUAL. THUS, INCORRECT.
