Spooky 3-Digit Subtraction - Halloween Maths Game for Lower Key ... - Free Printable

The image depicts a Halloween-themed interactive subtraction activity titled "Spooky Subtraction." The task involves solving subtraction problems and selecting the correct answers from a grid of options. Below, I will solve the two subtraction problems shown in the image and explain the solution step by step.

Problem 1: Solve the subtraction equation \( 645 - 321 \)

#### Step 1: Write the numbers vertically for subtraction.
\[
\begin{array}{c@{}c@{}c@{}c}
& 6 & 4 & 5 \\
- & 3 & 2 & 1 \\
\hline
\end{array}
\]

#### Step 2: Subtract the digits column by column, starting from the rightmost column (ones place).
- Ones place: \( 5 - 1 = 4 \)
- Tens place: \( 4 - 2 = 2 \)
- Hundreds place: \( 6 - 3 = 3 \)

#### Step 3: Combine the results.
\[
\begin{array}{c@{}c@{}c@{}c}
& 6 & 4 & 5 \\
- & 3 & 2 & 1 \\
\hline
& 3 & 2 & 4 \\
\end{array}
\]

So, \( 645 - 321 = 324 \).

Problem 2: Solve the subtraction equation \( 598 - 126 \)

#### Step 1: Write the numbers vertically for subtraction.
\[
\begin{array}{c@{}c@{}c@{}c}
& 5 & 9 & 8 \\
- & 1 & 2 & 6 \\
\hline
\end{array}
\]

#### Step 2: Subtract the digits column by column, starting from the rightmost column (ones place).
- Ones place: \( 8 - 6 = 2 \)
- Tens place: \( 9 - 2 = 7 \)
- Hundreds place: \( 5 - 1 = 4 \)

#### Step 3: Combine the results.
\[
\begin{array}{c@{}c@{}c@{}c}
& 5 & 9 & 8 \\
- & 1 & 2 & 6 \\
\hline
& 4 & 7 & 2 \\
\end{array}
\]

So, \( 598 - 126 = 472 \).

---

Final Answers

1. \( 645 - 321 = 324 \)
2. \( 598 - 126 = 472 \)

Thus, the solutions are:
\[
\boxed{324 \text{ and } 472}
\]
