00:00 Choose the appropriate sign
00:04 Let's start from point (-4) on the negative side of the axis
00:07 The number is oriented, positive
00:12 The positive direction on the axis is right, so we'll take 2 to the right
00:20 The number is oriented, negative
00:24 The negative direction on the axis is left, so we'll take 3 to the left
00:39 This is the solution for the left side
00:44 The further right the number is on the axis, the larger it is
00:46 And this is the solution to the question

Step-by-step solution

First let's solve the equation:

(4)+2+(3)= (-4)+2+(-3)=

We'll locate -4 on the number line and move two steps to the right (since 2 is greater than zero):

-11-10-9-8-7-6-5-4-3-2-101

This takes us to the number -2.

Now let's move three steps to the left (since minus 3 is less than zero):

-11-10-9-8-7-6-5-4-3-2-101

This takes us to -5.

The solution to the equation is:

(4)+2+(3)=5 (-4)+2+(-3)=-5

Therefore, since 5 5 is greater than 5 -5 , the missing sign must be: < < .
