, draw the arrow for −4; the sum is
.

Answer 1

Explanation:

To find -5 + 4, you can start at 0 and follow these steps:

Start at 0.

Draw an arrow to the left for -5.

Now, from where you ended up (-5), draw an arrow to the right for +4.

The sum is -1.

Now, to find -5 + (-4), you can follow similar steps:

Start at 0.

Draw an arrow to the left for -5.

From where you ended up (-5), draw another arrow to the left for -4.

The sum is -9.

So, -5 + 4 = -1, and -5 + (-4) = -9.
