Subtraction Facts up to (18 - 9) worksheet for math practice.

Problem Description:

The image contains a worksheet titled "Subtraction Facts up to (18 - 9) (A)." It consists of multiple subtraction problems, each involving numbers up to 18. The task is to solve each subtraction problem and calculate the differences.

Solution Approach:

To solve each subtraction problem, we will subtract the second number (the subtrahend) from the first number (the minuend) for every pair. Let's go through the worksheet step by step.

Final Answer:

The solutions to all the subtraction problems are as follows:

\[
\begin{array}{cccccccccc}
6 & 0 & 5 & 2 & 3 & 1 & 1 & 3 & 4 & 5 \\
6 & 2 & 0 & 1 & 7 & 5 & 3 & 2 & 8 & 6 \\
3 & 8 & 2 & 2 & 2 & 2 & 9 & 6 & 1 & 2 \\
2 & 8 & 9 & 2 & 4 & -2 & 11 & 3 & 8 & 0 \\
7 & 0 & 7 & 0 & 4 & 7 & 6 & 4 & 5 & 1 \\
1 & 1 & 9 & 1 & 7 & 9 & 0 & 0 & 5 & 8 \\
9 & 6 & 3 & 7 & 9 & 8 & 7 & 1 & 4 & 9 \\
