To solve the expression \( -12 - (-6) \), we can rewrite it:
\[ -12 + 6 \]
Now, we perform the addition:
\[ -12 + 6 = -6 \]
So, the value of \( -12 - (-6) \) is \(-6\).
The correct response is:
-6

To solve the expression \( -18.1 + 5 \), we can perform the addition:
\[ -18.1 + 5 = -18.1 + 5.0 \]
To add, we can think of it in terms of moving on the number line. Starting at \(-18.1\) and moving \(5\) units to the right:
\[ -18.1 + 5 = -13.1 \]
Thus, the value of \( -18.1 + 5 \) is \(-13.1\).
The correct response is:
-13.1

To calculate the value of \( -189.987 - 30.87 \), we perform the operation:
\[ -189.987 - 30.87 = -189.987 - 30.870 \]
When you add two negative numbers, you combine their absolute values:
\[ = - (189.987 + 30.87) \]
Now, let's calculate \( 189.987 + 30.87 \):
\[ 189.987 + 30.87 = 220.857 \]
Therefore,
\[ -189.987 - 30.87 = -220.857 \]
So, the value of \( -189.987 - 30.87 \) is \( -220.857 \).
The correct response is:
-220.857
