It looks like you entered a sequence of numbers or expressions. Let me interpret and solve this step by step.

Given:

$-3 \quad 4 - 5$

This can be broken down into two parts:

1. The number $-3$
2. The expression $4 - 5$

Let's evaluate the expression:

$4 - 5 = -1$

Now, we have:

$-3 \quad \text{and} \quad -1$

There is no arithmetic operation specified between $-3$ and $-1$, but if you were looking to add, subtract, multiply, or divide these two numbers, here are the results:

1. Addition: $-3 + (-1) = -4$
2. Subtraction: $-3 - (-1) = -2$
3. Multiplication: $-3 \times (-1) = 3$
4. Division: $-3 \div (-1) = 3$

Would you like to clarify the operation you intended, or would you like more details on any of these operations?
