-8 - -9 = -1 how do I put that on a number line ?
Crazy boy [7]

In order to put these numbers on a number line, you need to draw a number line and then count backwards to find your answer.

<h3>How do you put the equation on the number line?</h3>

The first thing to do is to draw a number line from -9 to 3.

Then look at the equation which is:

-8 - -9 = 1

-8 + 9 = 1

The two negatives become a positive.

Because the sign is positive, you will count backwards on the number line a total of 9 places. This will then take you to 1.

30 PTS <br> Please make sure everything is easy to understand
Semenov [28]
So for number one you would start with parentheses (-2 x 4) and that would get you -8 and then you would forget about the parentheses and drop everything else down and now the problem would be -8 x 3 and remember anytime you have a number by parentheses it’s multiplication and that dot by the parentheses also stands for multiplication so -8 x 3 would get you -24. You could also look at it as positive 8 x 3 and that would get you 24 and then you could just add that negative sign to the 24
