Order of Operations: First, we need to understand the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), often abbreviated as PEMDAS. In this expression, we have an exponent and a subtraction. According to PEMDAS, we must calculate the exponent before the subtraction.Calculate Exponent: Calculate the exponent part of the expression, which is 3^2. This means 3 multiplied by itself, which is 3 * 3 = 9.Subtract Result: Now, subtract the result of the exponent from the first number in the expression. This gives us 3 - 9.Perform Subtraction: Perform the subtraction: 3 - 9 equals -6.Check Final Result: Check the final result for any mathematical errors. The calculations were done according to the order of operations, and the subtraction was performed correctly.

3 - 3^2

Order of Operations: First, we need to understand the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), often abbreviated as PEMDAS. In this expression, we have an exponent and a subtraction. According to PEMDAS, we must calculate the exponent before the subtraction.
Calculate Exponent: Calculate the exponent part of the expression, which is `3^2`. This means `3` multiplied by itself, which is `3 * 3 =` 9.
Subtract Result: Now, subtract the result of the exponent from the first number in the expression. This gives us `3 -` 9.
Perform Subtraction: Perform the subtraction: `3 - 9` equals -6.
Check Final Result: Check the final result for any mathematical errors. The calculations were done according to the order of operations, and the subtraction was performed correctly.
