Solve the following expressions:
`3 + 2 - 1 xx 4 -: 2`

Answer

To solve the expression `3 + 2 - 1 x 4 ÷ 2`, we will follow the order of operations, often remembered by the acronym BODMAS (Brackets, Orders, Division and Multiplication (from left to right), Addition and Subtraction (from left to right)).

### Step-by-Step Solution:

1. **Identify the expression**:
\[ 3 + 2 - 1 \times 4 \div 2 \]

2. **Perform Division and Multiplication from left to right**:
- First, we will handle the multiplication and division in the expression.
- Start with `1 x 4`:
\[ 1 \times 4 = 4 \]
- Now the expression becomes:
\[ 3 + 2 - 4 \div 2 \]

3. **Next, perform the division**:
- Now we calculate `4 ÷ 2`:
\[ 4 \div 2 = 2 \]
- Now the expression simplifies to:
\[ 3 + 2 - 2 \]

4. **Perform Addition and Subtraction from left to right**:
- First, calculate `3 + 2`:
\[ 3 + 2 = 5 \]
- Now the expression is:
\[ 5 - 2 \]

5. **Finally, perform the subtraction**:
- Calculate `5 - 2`:
\[ 5 - 2 = 3 \]

### Final Answer:
The result of the expression `3 + 2 - 1 x 4 ÷ 2` is **3**.
