please solve the following problem and provide the answer with the explanation that can be easily understood by 9 years old or an adult who doesn't know much about solving math. "Write down the signs in the empty spaces to get the correct equation, parentheses may be used: 300 'box' 20 'box' 10 'box' 4 = 120."

Let's solve this puzzle step by step to make it easy to understand!

### Problem:  
You need to place signs (like `+`, `-`, `×`, or `÷`) between the numbers **300**, **20**, **10**, and **4** to make the equation equal to **120**. You can also use parentheses if needed.

### Step 1: Identify the Numbers  
The numbers we have are:
- 300
- 20
- 10
- 4

We need to use some mathematical operations (like adding, subtracting, multiplying, or dividing) between these numbers to get **120**.

### Step 2: Try Different Operations  
Let's test different operations until we get the correct equation.

1. Let's start by trying multiplication and division because they can change the size of the numbers quickly.

### Step 3: Start with Parentheses  
Parentheses help group numbers so that we do those operations first. Let's try this setup:

\[
\frac{300}{(20 + 10 + 4)}
\]

This setup divides 300 by the sum of the numbers in parentheses.

### Step 4: Calculate the Equation
First, let's solve the inside of the parentheses:

\[
20 + 10 + 4 = 34
\]

Now, we divide:

\[
\frac{300}{34} \approx 8.82
\]

This is not equal to 120, so we try something else.

### Step 5: Test Different Grouping
Let's try a new setup:

\[
(300 - 20) ÷ (10 ÷ 4)
\]

- First, solve inside the parentheses:
  
  \[
  300 - 20 = 280
  \]
  
  Now for the division part:
  
  \[
  10 ÷ 4 = 2.5
  \]
  
  Next, divide 280 by 2.5:
  
  \[
  280 ÷ 2.5 = 112
  \]

Still, not 120, but we're close! Let's adjust it one more time.

### Step 6: Try Multiplication and Addition  
How about this one:

\[
300 - 20 \times (10 - 4)
\]

Let's solve step by step:

1. Solve inside the parentheses first:
  
   \[
   10 - 4 = 6
   \]
  
2. Now multiply:
  
   \[
   20 \times 6 = 120
   \]
  
3. Finally, subtract:
  
   \[
   300 - 120 = 180
   \]

Still not quite right. We’re close again, but let’s try other groupings or a new strategy.
