The typical numbers used in assessing periodontal disease are depth of the periodontal pocket or sulcus. These are measurements (in millimeters) from the top of the gums to where the gums attach to the tooth. There are usually six points of measurement around each tooth. Three millimeters or less is considered healthy or normal, while higher measurements indicate disease.
Dentists and hygienists may also measure periodontal attachment loss, from the CEJ (neck of the tooth) to the depth of the pocket. This is simply another way of assessing periodontal disease. They can also assess mobility of the teeth and record how many areas bleed during these measurements.
Signed numbers are "plus" and "minus" numbers.
Because both minus signs to be cut therefore minus * minus will be treated as plus numbers

It is an axiom necessary for the real numbers to form a field.
-7
In math it is the answer of the biggest of the numbers minus the smallest of the numbers. :) ;)
= The sum of two numbers is -42 the first number minus the second number is 52 Find the numbers? =
Differance
The numbers are: -85.9 and -96.7
Answer: 453 The number given can be seen as a sequence of 63 60 56 51. Taking these as separate numbers: 60 is 63 minus 3 56 is 60 minus 4 51 is 56 minus 5 the numbers decrease by the (difference between the last two numbers plus 1) So, 51 minus 6 gives 45 and 45 minus 7 gives 38 The next three numbers are, therefore, 453
It depends on the variability of whatever it is that you are measuring.
