**Calculating the Value of a Mathematical Expression**

In this article, we will evaluate the mathematical expression:

**3/10^0 + 3/10^1 + 3/10^2**

To evaluate this expression, we need to follow the order of operations (PEMDAS):

- Calculate the powers
- Perform any multiplication or division operations
- Add or subtract operators

Let's break down the expression step by step:

### Calculating the Powers

First, let's calculate the powers:

**10^0**= 1 (any number raised to the power of 0 is 1)**10^1**= 10**10^2**= 100

So, the expression becomes:

**3/1 + 3/10 + 3/100**

### Performing Division Operations

Next, let's perform the division operations:

**3/1**= 3**3/10**= 0.3**3/100**= 0.03

The expression now becomes:

**3 + 0.3 + 0.03**

### Adding the Values

Finally, let's add up the values:

**3 + 0.3 = 3.3**
**3.3 + 0.03 = 3.33**

Therefore, the final value of the expression is:

**3.33**

In conclusion, the value of the mathematical expression **3/10^0 + 3/10^1 + 3/10^2** is **3.33**.
