Multiplication by 0 worksheet with 20 problems for learning basic math concepts.

Problem Analysis

The task involves solving multiplication problems, with a focus on the property of multiplying any number by 0. The key rule to remember is:

Any number multiplied by 0 equals 0.

This rule applies regardless of the other number involved in the multiplication.

Step-by-Step Solution

#### First Row:
1. \( 1 \times 0 = 0 \)
2. \( 0 \times 2 = 0 \)
3. \( 0 \times 4 = 0 \)
4. \( 6 \times 0 = 0 \)
5. \( 0 \times 5 = 0 \)

#### Second Row:
1. \( 0 \times 9 = 0 \)
2. \( 7 \times 0 = 0 \)
3. \( 3 \times 0 = 0 \)
4. \( 0 \times 8 = 0 \)
5. \( 0 \times 0 = 0 \)

#### Third Row:
1. \( 5 \times 0 = 0 \)
2. \( 0 \times 6 = 0 \)
3. \( 0 \times 2 = 0 \)
4. \( 0 \times 4 = 0 \)
5. \( 0 \times 8 = 0 \)

#### Fourth Row:
1. \( 7 \times 0 = 0 \)
2. \( 3 \times 0 = 0 \)
3. \( 0 \times 0 = 0 \)
4. \( 9 \times 0 = 0 \)
5. \( 9 \times 1 = 9 \) (Note: This is the only exception where 0 is not involved in multiplication.)

#### Fifth Row:
1. \( 0 \times 4 = 0 \)
2. \( 7 \times 0 = 0 \)
3. \( 0 \times 8 = 0 \)
4. \( 2 \times 0 = 0 \)
5. \( 0 \times 3 = 0 \)

Final Answers

Putting all the results together:

1. \( 0, 0, 0, 0, 0 \)
2. \( 0, 0, 0, 0, 0 \)
3. \( 0, 0, 0, 0, 0 \)
4. \( 0, 0, 0, 0, 9 \)
5. \( 0, 0, 0, 0, 0 \)

Boxed Final Answer

\[
\boxed{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 9, 0, 0, 0, 0, 0}
\]

Explanation

- Every multiplication involving 0 results in 0, except for the case where 9 is multiplied by 1, which equals 9.
- This exercise reinforces the fundamental property of multiplication by 0.
