The World of
Integers

Created by Isaiah B. and Michael W.

We are using the numbers .5, -5, 6, -3/4
.5 is larger than -5
-5 is les s than 6
6 is larger than -3/4
6 is larger than .5
.5 is larger than -3/4
-5 is less than -3/4

ordered from least to greatest
-5, -3/4, .5, 6

Graph
<-----(-5)----(-3/4) 0 (.5)-----(6)---->

Absolute Value
|-5| + |-3/4| = -5+3/4
|6| + |-5|= 11
|-3/4| + |.5|= 1+1/4
|.5| + |6| = 6.5

explanation
Absolute Value is the amount of space from zero.

addition: 5+123=128.........-10+36=26
Subtraction: 6-13=-7.........-3-10=-13
multiplication:(10)(20) = 200........ (-3)(10)=-30
division: 6/3=2........-50/2=-25
