Using the number line, write the integer which is
3 less than 2

Answer

To solve the problem of finding the integer that is 3 less than 2 using a number line, follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem**: We need to find the integer that is 3 less than 2. This means we will subtract 3 from 2.

**Hint**: Remember that "less than" indicates subtraction.

2. **Set Up the Calculation**: Write down the expression for the calculation:
\[ 2 - 3 \]

**Hint**: When you see "less than," think about how to represent that mathematically.

3. **Perform the Subtraction**: Calculate the result of the expression:
\[ 2 - 3 = -1 \]

**Hint**: When subtracting a larger number from a smaller number, the result will be negative.

4. **Locate the Result on the Number Line**: Now, we need to visualize this on a number line. Draw a number line with 0 in the center. Mark the positive integers (1, 2, 3, ...) to the right of 0 and the negative integers (-1, -2, -3, ...) to the left of 0.

**Hint**: The number line helps us visualize the position of integers relative to zero.

5. **Identify the Integer**: From the result of our calculation, we found that 3 less than 2 is -1. On the number line, -1 is located one unit to the left of 0.

**Hint**: Always count the units from zero to find the correct position on the number line.

### Final Answer:
The integer that is 3 less than 2 is **-1**.
