General Explanation of Using a Number Line for Subtraction
1.
Identify the Starting Point:
- The starting point on the number line is the first number in the subtraction equation (the minuend).
2.
Move Left:
- Subtracting means moving to the left on the number line.
- The number of steps you move to the left is equal to the second number in the equation (the subtrahend).
3.
Find the Ending Point:
- The point where you land after moving the required number of steps is the answer (the difference).
