## Key Concepts

These are the key concepts you need to understand to accurately answer the question.

###### sum of numbers

In this particular exercise, you need to find the sum of -3, 5, and -12.

To start:

- Identify the numbers you need to add. Here, the numbers are -3, 5, and -12.

The key is to add each number in sequence:

Adding -3 and 5 first gives you 2, and then you add the result to -12, giving you -10. Remember, the 'sum' means adding every number step by step.

###### simplifying expressions

Let's walk through the steps to make this clearer:

- Write out the expression: -3 + 5 + (-12).

When you add these, you get 2. So, the expression now looks like this: 2 + (-12).

Next, you add 2 to -12, which results in -10. By following these steps, you've simplified the original expression to its simplest form, -10.

###### basic arithmetic

It includes operations like addition, subtraction, multiplication, and division.

In this exercise, we focus on addition involving both positive and negative numbers:

- Add positive and negative numbers step by step.
- Remember the rules for adding positive and negative numbers: Adding a positive number increases the total, while adding a negative number decreases it.

Add -3 and 5 first, then take that result and add -12.

Understanding and practicing these basic arithmetic steps will greatly improve your math skills. Plus, you'll find it easier to handle more complex problems in the future.
