Let's denote the unknown number as \( x \). According to the problem statement, we can set up the equation:

\[ 10(x + (-1)) = -40 \]

This simplifies to:

\[ 10(x - 1) = -40 \]

Now, we can divide both sides by 10:

\[ x - 1 = -4 \]

Next, we can solve for \( x \) by adding 1 to both sides:

\[ x = -4 + 1 \]

\[ x = -3 \]

So, the number is \(-3\).

The correct response is:

−3 (negative 3).
