maybe you should try typing in your text, to improve your formatting. Just sayin' ... Eliminating all those linefeeds, you have
82+9(12÷3*2)−7
parens first; mult/div L-to-R:
82+9(4*2)-7 = 82+9(8)-7
now the rest of the mult/div:
82+72-7
now add/sub L-to-R:
154-7
147
To simplify the given expression, follow the Order of Operations (also known as PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to evaluate the expression step by step.
Step 1: Solve the expression inside the parentheses
12 ÷ 3 × 2 = 4 × 2 = 8
Step 2: Substitute the value back into the expression
8 ÷ 2 + 9 × 8 - 7
Step 3: Perform the multiplication and division operations from left to right
8 ÷ 2 + 72 - 7
Step 4: Perform the addition and subtraction operations from left to right
4 + 72 - 7
Step 5: Complete the addition and subtraction operations
76 - 7 = 69
Therefore, the simplified expression is 69.
