Integers- the set of whole numbers and their opposites (…,-3,-2,-1,0,1,2,3,…)
Opposites- the opposite of a number is found by going the same distance from zero on a number line, but in the opposite direction
- basically, you just have to change the sign to its opposite
Find the opposite of the following:
9___ -11___ -56___ 32 ___
Since the whole numbers are 0,1,2,3,… and the integers are described as the whole numbers and their opposites, then the integers are: …,-3,-2,-1,0,1,2,3,…
Integers or Not:
When you see this, it is asking for the absolute value of the number inside…12 in this case
In other words…how many units away from zero is 12 on a number line?
Since the absolute value is asking you about distance, will it ever be negative? Can you have a negative distance?
Find the following:
