The stock market gained 20 points on monday, lost 30 points on tuesday, and then lost another 15 points on wednesday. what was the gain or loss over the three days?

-25

Step-by-step explanation:

Given:

The stock market gain and loss.

Monday = +20

Tuesday = -30

Wednesday = -15

Here negative sign represents the loss and positive sign represents the gain.

Now let's calculate the gain or loss,

= +20 - 30 - 15

= +20 - 45

= -25

It is negative 25, therefore, it is a loss.

So, the loss over the three days -25.
