Order of Operations in Expressions

When evaluating mathematical expressions, it is important to follow the correct order of operations to ensure accurate results. The order of operations is commonly remembered using the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Let's apply this order of operations to the given expressions:

1. 15(543-84:7)=??? - First, we need to simplify the expression inside the parentheses: 543 - 84:7. - Next, we perform the division: 84 divided by 7, which equals 12. - Now, we substitute the result back into the expression: 543 - 12. - Finally, we perform the multiplication: 15 multiplied by the result of 543 - 12. - The final answer to the expression is 7,725.

2. : , . ... , : - Unfortunately, the given expression is incomplete and does not provide enough information to determine the order of operations or the values of the variables involved. Please provide additional context or information for a more accurate response.

3. . , , . ... - Similar to the previous expression, this one is also incomplete and lacks the necessary information to determine the order of operations or the values of the variables involved. Please provide additional context or information for a more accurate response.

4. , 12. ... . - Again, this expression is incomplete and does not provide enough information to determine the order of operations or the values of the variables involved. Please provide additional context or information for a more accurate response.

5. ... . ... . - Like the previous expressions, this one is also incomplete and lacks the necessary information to determine the order of operations or the values of the variables involved. Please provide additional context or information for a more accurate response.

6. ** - - , . , - . , . - , - , , . : , . | | , . , ** - Unfortunately, this expression is not clear and does not provide enough information to determine the order of operations or the values of the variables involved. Please provide additional context or information for a more accurate response.

7. **- , , , , , . - 2, , 3, 1 4 7. - , , . . ()** - This expression seems to involve a series of operations and numbers, but it is not clear how they are related or what the specific order of operations should be. Please provide additional context or information for a more accurate response.

8. ... : ? () ... . ... - Similar to the previous expressions, this one is also incomplete and lacks the necessary information to determine the order of operations or the values of the variables involved. Please provide additional context or information for a more accurate response.

9. ), ( 34 ), . - ... - Unfortunately, this expression is incomplete and does not provide enough information to determine the order of operations or the values of the variables involved. Please provide additional context or information for a more accurate response.

10. . 18:6+513-5(91-84) = 64:8+9:9-63:7 ... - First, we need to simplify the expression inside the parentheses: 91 - 84. - Next, we perform the subtraction: 91 - 84, which equals 7. - Now, we substitute the result back into the expression: 18:6 + 513 - 5 * 7. - Next, we perform the multiplication: 5 multiplied by 7, which equals 35. - Now, we substitute the result back into the expression: 18:6 + 513 - 35. - Finally, we perform the division: 18 divided by 6, which equals 3. - Now, we substitute the result back into the expression: 3 + 513 - 35. - Finally, we perform the addition and subtraction from left to right: 3 + 513 equals 516, and 516 - 35 equals 481. - The final answer to the expression is 481.
