Math worksheet for practicing multiplication by 2 with problems and a chart to fill in.

Problem Overview:

The task involves multiplying each number by 2 and filling in the results. Additionally, a multiplication chart for the table of 2 needs to be completed.

Step-by-Step Solution:

#### Part 1: Multiply Each Number by 2
We are given a set of numbers to multiply by 2. Let's calculate each one:

1. \( 4 \times 2 = 8 \)
2. \( 7 \times 2 = 14 \)
3. \( 10 \times 2 = 20 \)
4. \( 2 \times 2 = 4 \)
5. \( 0 \times 2 = 0 \)
6. \( 12 \times 2 = 24 \)
7. \( 8 \times 2 = 16 \)
8. \( 9 \times 2 = 18 \)
9. \( 6 \times 2 = 12 \)
10. \( 1 \times 2 = 2 \)
11. \( 5 \times 2 = 10 \)
12. \( 3 \times 2 = 6 \)

So, the results are:
- \( 4 \times 2 = 8 \)
- \( 7 \times 2 = 14 \)
- \( 10 \times 2 = 20 \)
- \( 2 \times 2 = 4 \)
- \( 0 \times 2 = 0 \)
- \( 12 \times 2 = 24 \)
- \( 8 \times 2 = 16 \)
- \( 9 \times 2 = 18 \)
- \( 6 \times 2 = 12 \)
- \( 1 \times 2 = 2 \)
- \( 5 \times 2 = 10 \)
- \( 3 \times 2 = 6 \)

#### Part 2: Complete the Multiplication Chart for the Table of 2
The multiplication chart is a table where the row represents the multiplier (in this case, 2), and the columns represent the numbers being multiplied. We need to fill in the results for \( 2 \times 1, 2 \times 2, \ldots, 2 \times 10 \).

Let's calculate each entry:

- \( 2 \times 1 = 2 \)
- \( 2 \times 2 = 4 \)
- \( 2 \times 3 = 6 \)
- \( 2 \times 4 = 8 \)
- \( 2 \times 5 = 10 \)
- \( 2 \times 6 = 12 \)
- \( 2 \times 7 = 14 \)
- \( 2 \times 8 = 16 \)
- \( 2 \times 9 = 18 \)
- \( 2 \times 10 = 20 \)

So, the completed multiplication chart is:

\[
\begin{array}{c|cccccccccc}
\times & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 \\
\hline
2 & 2 & 4 & 6 & 8 & 10 & 12 & 14 & 16 & 18 & 20 \\
\end{array}
\]

Final Answer:

\[
\boxed{
\begin{array}{c|cccccccccc}
\times & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 \\
\hline
2 & 2 & 4 & 6 & 8 & 10 & 12 & 14 & 16 & 18 & 20 \\
\end{array}
}
\]
