To solve our problem, we'll use a familiar tool: the** times table**.

When multiplying stacked numbers, start with the **right digit** on the **bottom**. The bottom number only has one digit: 4.

We'll multiply 4 by the top number, 2.3. Since there's no 2.3 in the times table, we'll have to multiply one digit at a time.

As usual, we'll solve the problem from **right to left**. So, we'll multiply 4 by the digit on the **top right**. Here, that's 3.

Now it's time to solve 4 x 3. We can use the **times table**.

4 x 3 is 12, but there's no room to write both digits underneath the 4 and 3.

Remember, this means we'll have to **carry**. We learned about carrying numbers in the lesson on multiplying larger numbers.

We'll write the right digit, 2, under the line...

We'll write the right digit, 2, under the line...then we'll carry the left digit, 1, up to the **next** set of digits in the problem.

Now it's time for the next step. We'll multiply 4 x 2.

4 x 2 = 8. But we won't write 8 under the line yet. Remember, there's one more step.

We need to make sure we **add** the number we carried: 1.

We'll set up our addition problem.

1 + 8 = 9.

We'll write 9 beneath the line.

In our problem, we multiplied a decimal number: 2.3. This means our answer will also need to be a decimal number.

Let's figure out where to put the **decimal point **(**.**).

In the problem, 2.3 has **one** digit to the **right** of the decimal point.

This means our answer will also have** one** digit to the **right** of the decimal point.

We'll place the decimal point so that only **one** digit is to the** right**: the 2.

Our problem is solved. The total is 9.2. We know that 2.3 x 4 = 9.2. We can read this answer as **nine and two-tenths**.

Let's try another problem. This time we'll multiply money: $3.05 x 2.

First, we'll multiply the bottom number, 2, by the digit on the top right. That's 5.

2 x 5 = 10.

We'll write the 0 under the line...

We'll write the 0 under the line...and carry the 1. We'll place it above the next digit.

The next digit is 0.

Anything times zero is zero, so we know that 2 x 0 = 0.

Remember, we need to make sure we add the 1 that we carried.

0 + 1 = 1. We'll write 1 beneath the line.

Finally, we'll multiply 2 and 3.

2 x 3 = 6, so we'll write 6 beneath the line.

It's time to place our decimal point. We need to **count** the digits to the **right** of the decimal point in our problem.

3.05 has **two** digits to the right of the decimal point. They're 0 and 5.

This means our answer will need to have **two** digits to the right of the decimal point.

We'll place the **decimal point** so that **two** digits are to the right: the 1 and the 0.

Finally, we'll write a **dollar sign** ($) to the left of the number.

We've solved the problem. $3.05 x 2 = $6.10. We can read this as **six dollars and ten cents**.
