To find the number that you need to subtract from -2.32 to get 2.3, you can set up the equation:
\[ -2.32 - x = 2.3 \]
To solve for \(x\), you can rearrange the equation:
\[ -x = 2.3 + 2.32 \]
Calculating the right side:
\[ -x = 4.62 \]
Now, multiply by -1 to solve for \(x\):
\[ x = -4.62 \]
So, -2.32 minus -4.62 equals 2.3.
