00:00 Choose the appropriate sign
00:04 Find the point (-3) on the axis
00:08 Positive multiplied by negative always equals negative
00:12 Let's take 3 jumps left (to the negative side) on the axis
00:17 Positive multiplied by negative always equals negative
00:22 Let's take 3 jumps left (to the negative side) on the axis
00:27 This is the solution for the left side, now let's calculate the right side
00:31 Find the point (3) on the axis
00:34 Let's take 3 jumps right (to the positive side) on the axis
00:38 And again let's take 3 jumps right (to the positive side) on the axis
00:44 This is the solution for the right side
00:53 And this is the solution to the question

1

Understand the problem

−3+(−3)+(−3)?3+3+3 -3+(-3)+(-3)?3+3+3

2

Step-by-step solution

Let's remember the laws:

−(−x)=+x -(-x)=+x

+(−x)=−x +(-x)=-x

We'll solve the left side first.

Let's write the exercise in the appropriate form:

−3−3−3= -3-3-3=

We'll solve the exercise from left to right:

−3−3=−6 -3-3=-6

−6−3=−9 -6-3=-9

Now let's solve the right side:

3+3+3= 3+3+3=

3+3=6 3+3=6

6+3=9 6+3=9

Since the right side is larger, the appropriate sign will be:

−9<9 -9 < 9
