Solve 300-(80-120): Order of Operations with Integer Subtraction

To solve the expression $300 - (80 - 120)$, we'll follow these steps:

• Step 1: Evaluate the expression within the parentheses.
• Step 2: Substitute the evaluated result into the overall expression.
• Step 3: Perform arithmetic operations to find the solution.

Now, let's evaluate the expression:

Step 1: Inside the parentheses, we calculate:

$80 - 120 = -40$

Step 2: Substitute this result back into the main expression, which becomes:

$300 - (-40)$

Step 3: Address the subtraction of a negative number, which effectively becomes addition:

$300 + 40 = 340$

Therefore, the solution to the problem is $340$.
