Problem Description:
The task is to solve a series of subtraction problems. The worksheet contains 20 subtraction equations, and the goal is to find the difference for each equation.
Solution Approach:
1.
Understand Subtraction: Subtraction involves taking one number (the subtrahend) away from another number (the minuend). The result is called the difference.
2.
Perform Each Calculation: For each equation, subtract the second number from the first number.
3.
Organize the Answers: Write the answers in the provided spaces next to each equation.
Step-by-Step Solution:
#### First Column:
1. \( 30 - 20 = 10 \)
2. \( 35 - 15 = 20 \)
3. \( 30 - 10 = 20 \)
4. \( 39 - 20 = 19 \)
5. \( 27 - 13 = 14 \)
6. \( 42 - 9 = 33 \)
7. \( 30 - 15 = 15 \)
8. \( 29 - 25 = 4 \)
9. \( 33 - 19 = 14 \)
10. \( 20 - 10 = 10 \)
#### Second Column:
11. \( 32 - 21 = 11 \)
12. \( 30 - 15 = 15 \)
13. \( 22 - 14 = 8 \)
14. \( 30 - 10 = 20 \)
15. \( 25 - 20 = 5 \)
16. \( 22 - 15 = 7 \)
17. \( 39 - 13 = 26 \)
18. \( 37 - 17 = 20 \)
19. \( 40 - 20 = 20 \)
20. \( 31 - 16 = 15 \)
Final Answer:
\[
\boxed{
\begin{array}{ll}
1. 10 & 11. 11 \\
2. 20 & 12. 15 \\
3. 20 & 13. 8 \\
4. 19 & 14. 20 \\
5. 14 & 15. 5 \\
6. 33 & 16. 7 \\
7. 15 & 17. 26 \\
8. 4 & 18. 20 \\
9. 14 & 19. 20 \\
10. 10 & 20. 15 \\
\end{array}
}
\]
Explanation:
Each subtraction problem was solved by directly subtracting the smaller number from the larger number. The results are clearly shown above, organized in the same format as the original worksheet. This method ensures accuracy and clarity in solving basic arithmetic problems.
