Well I believe you may be referring to the fact that whenever you subtract you actually "add the opposite." Another phrase people may use is to "plus a negative." This is not as accurate as add the opposite. An example would 12-5. It can be written as 12 + -5. You are simply adding the opposite of positive 5 which is negative 5. Now this may seem silly, but where it is useful is when you have a lot of negatives. For example. -10- -5. For some this is confusing until we add the opposite. I can rewrite this as -10 + 5. I simply took the opposite of -5 which was positive 5 and added it to -10. This equals -5. Hope this helps.

We use Q for Rationals... which is repreentative of Quocentia (Quotient), since rationals are RATIOs or fractions.
you can add your integers as addition and round them to simplest form.
No - because it can be represented as a ratio of integers : 81 = 81/1 Any number that can be represented as a ratio of 2 integers is classified as a rational number (other than that you can't use 0 for the denominator)
You can use the same symbols that you use to compare integers or decimals: equal, greater than, greater-than-or-equal, etc.
Subtracting an integer is the same as adding the additive inverse. In symbols: a - b = a + (-b), where "-b" is the additive inverse (the opposite) of b.
to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..
if they are two positive numbers, do it normally.If there is a negative and a positive, change it to addition and switch the SECOND integer sign. Only works with two integers in a subtraction question.Example: (-32)-(+2)= (-34) / (-32)+(-2)=(-34)
To find the sum of integers, you use addition.To find the difference, you use subtraction.
ADDING: same sign, add and keep that sign. opposite sides, subtract their absolute values and use the sign of the number with the larger absolute value SUBRTRACTING: change the sign of the subtrahend (2nd number) then ADD using rules above.
There are several different ways that you can use integers in everyday situations. For example you can use integers in the Winter, you use them with the temperature.
to make the integer zero for example: 2x+7y=7x+9 in this step's need to transpose 7x to the left member, 2x-7x+7y=7x-7x+9 look! it become zero and 7x is already transpose to the left member then that's the purpose of adding its opposite We use the opposite of a real numbers to distinguish the number from a negative number. The opposites of reals are real, whereas negative numbers are imaginary numbers. In the above example values and variables are assumed to be real.
The Chinese and Hindu were the first to use negative integers
use numbers
Are you sure you typed this correctly? Using normal methods this not factorable -- it si PRIME for the integers. You can use the quadratic formula, but that gives irrational answers for this quadratic.
Personally, I use them to count with.
