Evaluate the following :
`|7|-|-3|`

Answer

To evaluate the expression `|7| - |-3|`, we will follow these steps:

### Step 1: Evaluate the absolute values
The absolute value of a number is its distance from zero on the number line, regardless of direction.

- For `|7|`, since 7 is positive, `|7| = 7`.
- For `|-3|`, since -3 is negative, `|-3| = 3`.

### Step 2: Substitute the absolute values back into the expression
Now we substitute the absolute values we calculated back into the expression:

`|7| - |-3|` becomes `7 - 3`.

### Step 3: Perform the subtraction
Now we simply perform the subtraction:

`7 - 3 = 4`.

### Final Answer
Thus, the value of the expression `|7| - |-3|` is **4**.
