The problem asks us to perform several multiplication operations on whole numbers. Specifically, we need to solve: 1. $32 \times 3$

1. Problem Description

The problem asks us to perform several multiplication operations on whole numbers. Specifically, we need to solve:

1. $32 \times 3$

2. $432 \times 6$

3. $123 \times 15$

4. $432 \times 12$

2. Solution Steps

1. Solve $32 \times 3$:

$2 \times 3 = 6$

$3 \times 3 = 9$

So, $32 \times 3 = 96$

2. Solve $432 \times 6$:

$2 \times 6 = 12$. Write down 2, carry over

1. $3 \times 6 = 18$. $18 + 1 = 19$. Write down 9, carry over

1. $4 \times 6 = 24$. $24 + 1 = 25$. Write down

2

5. So, $432 \times 6 = 2592$

3. Solve $123 \times 15$:

First, multiply $123 \times 5$:

$3 \times 5 = 15$. Write down 5, carry over

1. $2 \times 5 = 10$. $10 + 1 = 11$. Write down 1, carry over

1. $1 \times 5 = 5$. $5 + 1 = 6$. Write down

6. So, $123 \times 5 = 615$.

Next, multiply $123 \times 10$:

$123 \times 10 = 1230$.

Finally, add the two results:

$615 + 1230 = 1845$.

So, $123 \times 15 = 1845$

4. Solve $432 \times 12$:

First, multiply $432 \times 2$:

$2 \times 2 = 4$

$3 \times 2 = 6$

$4 \times 2 = 8$

So, $432 \times 2 = 864$.

Next, multiply $432 \times 10$:

$432 \times 10 = 4320$.

Finally, add the two results:

$864 + 4320 = 5184$

So, $432 \times 12 = 5184$

3. Final Answer

1. $32 \times 3 = 96$

2. $432 \times 6 = 2592$

3. $123 \times 15 = 1845$

4. $432 \times 12 = 5184$
