RULES OF ADDITION OF INTEGERS

__ADDITION OF INTEGERS __

__Addition Rules of Integers –__

**a) To add two
positive integers, add their absolute values, and attach the positive sign.**

**b)To add two negative
integers, add their absolute values and attach the negative sign and to add two
integers of opposite signs, find the difference of their absolute values and
attach the sign of the integer with the greater absolute value.**

**If a, b, c are the
integers then- a + b = b + a**

**
(a+b) + c = a + (b+c) = a + b + c**

**The sum of any
integer and zero ‘0’ is the integer itself. In other words, if a is an integer then.**

**
a + 0 = a, zero here is nothing but additive identity.**

**Addition
of two or more integers of same sign – **

**To add the two or
more integers with the same sign (negative & positive), first we have to add
and find their absolute value and then attach the common sign with the obtained
value.**

**Example.1)
Add (+120) & (+65)**

**So, (+120) +
(+65) = 120 + 65 = 185 (Ans.)**

**Example.2)
Add (-35) & (-75)**

**So, (-35) + (-75) =
-110 (Ans.)**

**Addition of two or more integers with opposite sign – **

**a) First we have the
find the absolute value of given integers **

**b) subtract the
smaller absolute value from the bigger absolute value.**

**c) to the difference
in step 2, attach the sign of the integers which has the larger absolute value**

**Example.1)
Add (-45) & (+10)**

**(-45) + (+10) = -45 +
10 = -35 (Ans.)**
