### Integers

1. 1. INTEGERSIntegers form a bigger collection of numberswhich contains whole numbers andnegative numbers. For example-…-4, -3, -2,-1, 0, 1, 2, 3….
2. 2. TYPES OF INTEGERSPOSITIVEINTEGERS- 1, 2, 3,4…i.e. the natural numbersare called positive integers.NEGATIVEINTEGERS- -1, -2, -3,-4… are called negativeintegers.On a number line points tothe right of zero arepositive integers and thepoints to the left of zeroare negative.
3. 3. ZEROZero is neithernegative norpositive. It isgreater thanevery negativeinteger andsmaller thanevery positiveinteger.
4. 4. MATHEMATICAL APPLICATIONS OF INTEGERSThe sum of two integers is also an integer.Example: -5 +7=+2The difference of two integers is also an integer.Example: +8-(-4)=8+4=12The product of two positive integers is alwayspositive. Example:+8 x +4 =32The product of two negative integer is alwayspositive. Example: -3 x -4 =+12The product of a positive integer with a negativeinteger is negative. example: +3 x -2=-6.The product of zero and an integer is alwayszero. Example: 0x 2=0
