Evaluate the following
`40xx3-:6`

Answer

To evaluate the expression `40xx3-:6`, we first need to clarify the expression. It seems like there might be a typographical error in the expression as "xx" and "-" are not standard mathematical operations. Assuming the expression is meant to be `40 * 3 / 6`, we can proceed with the evaluation.

Let's break down the steps:

1. **Identify the operations**: The expression consists of multiplication and division. According to the order of operations (BODMAS/BIDMAS), we perform division before multiplication.

2. **Perform the division**: First, we will divide 3 by 6.
\[ 3 \div 6 = 0.5 \]

3. **Multiply the result by 40**: Now, we multiply the result from the division step by 40.
\[ 40 \times 0.5 = 20 \]

4. **Final answer**: The final result of the expression `40 * 3 / 6` is 20.

### Summary of Steps:
1. Identify the operations.
2. Perform the division: \(3 \div 6 = 0.5\).
3. Multiply the result by 40: \(40 \times 0.5 = 20\).
4. The final answer is 20.
