3 ways of computing the sum on the number line are:

  • Start at 8, then move 2 units to the left, then move 3 units to the left.
  • Start at -3, then move 8 units to the right, then move 2 units to the left.
  • Start at -2, then move 3 units to the left, then move 8 units to the right.

How to do the sum in three different ways on a number line?

Here we have the sum:

8 + (-3) + (-2)

The first way of doing the sum in a number line is starting on the first number, which is 8.

  • Then, we move 3 units to the left, to the 5.
  • Then, we move other 2 units to the left, to the 3.

Now, we also can think the sum as:

(-3) + 8 + (-2)

So now we can start at the value -3, then move 8 units to the right, and then 2 units to the left.

Or think the sum as:

(-2) + (-3) + 8

So we start at -2, then we move 3 units to the left, and finally 8 units to the right.

So the different ways of computing the sum on a number line depends on where we start.
