To subtract a number, we follow these steps:
1. Rewrite the Subtraction Problem as an Addition Problem:
When subtracting a negative number, the two negatives become a positive. Thus, \( -10 - (-6) \) can be rewritten as \( -10 + 6 \).
2. Combine the Numbers:
Now we simply add the two numbers:
\( -10 + 6 \).
3. Perform the Addition:
Start from \(-10\) and move 6 units to the right on the number line (because we are adding a positive number).
[tex]\[
-10 + 6 = -4
\][/tex]
Therefore, the result of the subtraction [tex]\( -10 - (-6) \)[/tex] is [tex]\(-4\)[/tex].
