Question

Marco tried to evaluate an expression. Here is his work:
7+3232–14
=
7+362–14 Step 1
=
7+3(36–14) Step 2
=
7+322 Step 3
=
7+66 Step 4
=
73 Step 5
Is Marco's work correct?




Questions

Answer 1

To evaluate Marco's work, let's review his steps carefully:

1. **Original Expression:**
\[
7 + 3232 - 14
\]

2. **Step 1:**
\[
7 + 362 - 14
\]
Here, Marco seems to have incorrectly changed \(3232\) into \(362\). This step is incorrect.

Since Step 1 is incorrect, all subsequent steps are based on this mistake. Let's evaluate the original expression correctly:

\[
3232 - 14 = 3218
\]

Then add that to 7:

\[
7 + 3218 = 3225
\]

Therefore, Marco's final answer is incorrect because his calculations started with an erroneous transformation of the numbers. The correct evaluation of the expression \(7 + 3232 - 14\) yields \(3225\).

In summary, Marco's work is **not correct**.
