descriptions and equations to the table to complete the explanation.

Answer 1

When we subtract 10 from 40, we get -10, not -40.

Step-by-step explanation:

To understand why 4-10 equals -40, we can start with the equation 4.0 = 0

If we multiply both sides of the equation by 10, we get 40 = 0

Now, if we subtract 10 from both sides of the equation, we have 40 - 10 = 0 - 10, which simplifies to 30 = -10

Therefore, by subtracting 10 from 40, we get -10, not -40.
