Notes for CBSE Class 6 Maths-Chapter 6 Integers

                         CHAPTER 6 INTEGERS
 
POSITIVE NUMBERS
Numbers greater than zero are called positive numbers.
 
NEGATIVE NUMBERS
Numbers less than zero are called negative numbers.
 
In the case of negative integers, greater the number, lesser its value. i.e. -6 < -2
 
ADDITION

• Numbers with the same sign are simply added and the sum has the same sign as that of the numbers.

E.g. (+5) + (+7)= (+12)  and (-5) + (-7)= (-12)

• Numbers with different signs are actually subtracted and the difference has the sign of the greater number.

E.g. (+5) + (-7)= (-2) and (-5) + (+7)= (+2)
 
ADDITIVE INVERSE
If two numbers are added to each other and the sum is zero, the numbers are said to be the additive inverse of each other.
E.g. (+5)+(-5) = 0 therefore (+5) and (-5) are additive inverse of each other.
