Assignment - 01-understanding Integers
Integers - any whole number, positive, negative or 0.
Positive Integer - Any whole number greater than 0. Opposite of negative.
Negative Integer - Any whole number less than 0. Opposite of positive.
Zero - Neither positive nor negative. The opposite of 0 is 0.
If we were look at a number line, the positive numbers will always go to the right, the negative numbers will always go to the left. Zero will be right in the middle of the two.
Absolute Value - a numbers distance away from zero. Absolute value is always positive as a distance is always a positive thing. Absolute value is represented by two vertical lines around a number: |-6|
Looking at the number line above, point M is located at -6. Because it is 6 units away from 0, it’s absolute value is 0, or |-6| = 6.
Point P is located at 3 on the number line. Because it is 3 units away from 0, it’s absolute value is 3, or |3| = 3.
Questions for this unit might look like this:
Look at the number line above. Write the integer that each point is located on. Also give its opposite and absolute value.
A : The integer is 0. The opposite is 0. The absolute value is 0.
B : The integer is -2. The opposite is 2. The absolute value is 2.
D : The integer is 6. The opposite is -6. The absolute value is 6.
