Answer 1

To simplify the expression using the order of operations, follow these steps:

1. First, perform any calculations within parentheses or brackets. In this case, there are none.

2. Next, perform any calculations involving exponents or roots. There are none in this expression.

3. Then, perform any multiplication or division from left to right.

In the expression, the division operation comes first.
4 ÷ 2 = 2

4. After performing division, perform any addition or subtraction from left to right.

12 - 23 + 2 + 24

Now, perform the subtraction operation:
12 - 23 = -11

Next, perform the addition operation:
-11 + 2 = -9

Finally, perform the last addition operation:
-9 + 24 = 15

Therefore, the simplified expression is 15.
