3.1 × 22 + 6 ÷ 2 - (3.9 + 3.3)
\(\sf3.1\times22+6\div2-(3.9+3.3)\)PEMDAS, parenthesis first:\(\sf3.1\times22+6\div2-7.2\)Now multiply:\(\sf68.2+6\div2-7.2\)Divide:\(\sf68.2+3-7.2\)Add:\(\sf71.2-7.2\)Subtract:\(\sf64\)
You have to use PEMDAS which is Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. The answer would be 29.9.
