User: how to multiply whole number and fraction?
Assistant: To multiply a whole number by a fraction, you can follow these steps:

1. **Write the whole number as a fraction**: You can do this by putting the whole number over 1. For example, if you want to multiply 3 by the fraction \(\frac{2}{5}\), you can express 3 as \(\frac{3}{1}\).

2. **Multiply the numerators**: Multiply the numerator (the top part) of the fraction by the numerator of the whole number (which is now a fraction). In our example, the numerator of the whole number is 3 and the numerator of the fraction is 2. So, \(3 \times 2 = 6\).

3. **Multiply the denominators**: Multiply the denominator (the bottom part) of the fraction by the denominator of the whole number (which is 1). In our case, \(1 \times 5 = 5\).

4. **Combine the results**: The new fraction will be the product of the numerators over the product of the denominators. So, you have \(\frac{6}{5}\).

5. **Simplify if necessary**: The fraction \(\frac{6}{5}\) is already in its simplest form, but if there were a common factor, you would divide both the numerator and the denominator by that factor.

Thus, \(3 \times \frac{2}{5} = \frac{6}{5}\).

User: how to add and subtract fraction and whole number?
Assistant: To add or subtract a fraction and a whole number, you'll need to follow these steps:

### Step 1: Convert the Whole Number to a Fraction
First, convert the whole number into a fraction by putting it over 1. For instance, if you're working with the whole number 3, it becomes \(\frac{3}{1}\).

### Step 2: Make Denominators the Same
To add or subtract fractions, you need a common denominator. If the fraction has a different denominator than 1, you'll need to find a common denominator.

For example:
- If you want to add \(3\) (which is \(\frac{3}{1}\)) and \(\frac{2}{5}\):
  - Find a common denominator (in this case, \(5\)).
  - Convert \(\frac{3}{1}\) to a fraction with a denominator of \(5\): 
    \[
    \frac{3}{1} = \frac{3 \times 5}{1 \times 5} = \frac{15}{5}
    \]

### Step 3: Perform the Addition or Subtraction
Now that both numbers are fractions with the same denominator, you can proceed. 

- For addition:
  \[
  \frac{15}{5} + \frac{2}{5} = \frac{15 + 2}{5} = \frac{17}{5}
  \]

- For subtraction:
  \[
  \frac{15}{5} - \frac{2}{5} = \frac{15 - 2}{5} = \frac{13}{5}
  \]

### Conclusion
Thus:
- To **add**: \(3 + \frac{2}{5} = \frac{17}{5}\)
- To **subtract**: \(3 - \frac{2}{5} = \frac{13}{5}\)

### Step 4: Simplify if Necessary
If your final fraction can be simplified, do so. Also, if it’s an improper fraction (the numerator is larger than the denominator), you might want to convert it into a mixed number.

User: what is TOR?
Assistant: TOR can refer to several things depending on the context, but the most common meanings are:

1. **TOR (The Onion Router)**: This is a free and open-source software that allows users to browse the internet anonymously. It works by routing internet traffic through a network of servers (known as Tor relays) to conceal a user's location and usage from surveillance and traffic analysis. It is often used to access the dark web or for privacy-focused activities.

2. **TOR (Terms of Reference)**: In project management and research, a Terms of Reference document defines the purpose and structure of a project, including objectives, scope, and stakeholders. It serves as a guideline for what needs to be accomplished.

3. **TOR (Total Operational Readiness)**: This is used in military or certain business operations contexts to indicate the state of being fully prepared to perform an operation or mission.

4. **TOR (Torsion)**: In a physics or engineering context, it can refer to torsion, which is the twisting of an object due to an applied torque.

If you have a specific context in which you're referring to "TOR," please provide more details for a more precise explanation!
