Answer :

Of course! Let's break down the expression step-by-step and solve it:

We need to calculate the sum of the following numbers:
[tex]\[ -10 + (-2) + (+3) + (-15) \][/tex]

Here's how we can solve it step-by-step:

1. First, manage the addition of the first two numbers:
[tex]\[ -10 + (-2) = -10 - 2 = -12 \][/tex]

2. Next, add the third number to the result:
[tex]\[ -12 + (+3) = -12 + 3 = -9 \][/tex]

3. Finally, add the last number to the result:
[tex]\[ -9 + (-15) = -9 - 15 = -24 \][/tex]

So, when we combine all the steps together, we get:
[tex]\[ -10 + (-2) + (+3) + (-15) = -24 \][/tex]

Therefore, the result is [tex]\( -24 \)[/tex].
