-1.56 minus what equals 1.4

Answer 1

To find out what number you need to subtract from -1.56 to get 1.4, you can set up the equation:

\[ -1.56 - x = 1.4 \]

Now, solve for \( x \):

1. Add \( x \) to both sides: \[ -1.56 = 1.4 + x \]

2. Subtract 1.4 from both sides: \[ -1.56 - 1.4 = x \]

3. Calculate the left side: \[ -1.56 - 1.4 = -2.96 \]

So, \[ x = -2.96 \]

Therefore, -1.56 minus -2.96 equals 1.4.
