To subtract \(-872\) from \(-684\), you can rewrite the expression as:
\[ -684 - (-872) \]
Subtracting a negative number is the same as adding its positive counterpart:
\[ -684 + 872 \]
Now, you can perform the addition:
\[ 872 - 684 = 188 \]
Since \(872\) is greater than \(684\), the result will be positive. Therefore:
\[ -684 - (-872) = 188 \]
So, \(-684 - -872 = 188\).
