Question

Which expression is equivalent to 8 + 4 + 4 • 2 + 3

Answer 1

To simplify the expression \( 8 + 4 + 4 \cdot 2 + 3 \), we follow the order of operations, which states that we should perform multiplication before addition.

1. First, calculate the multiplication:
\[
4 \cdot 2 = 8
\]

2. Now, substitute back into the expression:
\[
8 + 4 + 8 + 3
\]

3. Next, we perform the addition from left to right:
- Start with \( 8 + 4 \):
\[
8 + 4 = 12
\]
- Add \( 8 \):
\[
12 + 8 = 20
\]
- Finally, add \( 3 \):
\[
20 + 3 = 23
\]

Thus, the expression \( 8 + 4 + 4 \cdot 2 + 3 \) simplifies to \( 23 \). Therefore, the final answer is:

\[
\boxed{23}
\]
