    INTEGERS
  • 2. INTEGERS
    Q1. What are integers ?
    A1. The First numbers to be discovered were natural numbers i.e.1, 2,3,4,… After including Zero to them we get whole numbers. But there are negative numbers too. If we put whole numbers and negative together, the new collection is called Integers.
  • 3. INTEGERS
    TYPES OF INTEGERS
    1. Positive Integers- The positive numbers are called positive Integers e.g. 1,2,3,4,…
    2. Negative Integers-The negative numbers are called Negative Integers e.g. -1,-2,-3,-4,….
  • 4. INTEGERS
    ORDERING OF INTEGERS
    The numbers on the right side of zero on number line will be the bigger one, i.e. 0<1<2<3<4,….
    The numbers on the left side of Zero on Number line will be smaller one, i.e. 0>-1>-2>-3>-4,…..
  • 5. INTEGERS
    ADDITION AND SUBTRACTION WITH THE SAME SIGN
    We add the two positive Integers like(+3)+(+2) = +5 [=3+2]
    We also add when we have two negative Integers but the answer will take a minus (-) sign like (-2) +(-1)= -(2+1)= -3
  • 6. INTEGERS
    ADDITION OF INTEGERS OF DIFFERENT SIGN
    When we have one positive and one negative integer, we must subtract , but the answer will take the sign of the bigger integer. ( Ignoring the sign of the numbers decide which is bigger)
    Example:- (+5) + (-8) = (5-8) = -3
    (+6) + (- 4) = ( 6 – 4) = +2
  • 7. INTEGERS
    USES OF INTEGERS IN DAILY LIFE
    Every day in our daily life we use the integers for calculations .
    The figures are taken in positive and negative terms and it becomes possible to do the calculations. This can be understood by the following examples.
  • 8. INTEGERS
    SOME EXAMPLES ARE :
    1. (-3) +(+4)
    = -3+4
    = +1
    2. ( +5 ) + (+8)
    = +5+8
    =+13
  • 9. INTEGERS
    3. (-4)+ (+9)
    = -4+9
    = +5
    4. (-6)+(+1)
    = -6+1
    = -5
  • 10. INTEGERS
    RULES FOR MULTIPLICATION
    (-) x (+) = (-)
    (-) x ( -) = ( +)
    (+ ) x ( +) = ( +)
    (+ ) x ( - ) = ( - )
    FROM THE ABOVE RULES IT IS CLEAR THAT REMEMBERING THE SIGN RULES IS VERY IMPORTANT IN SOLVING INTEGERS PROBLEMS OF MULTILICATION.
  • 11. INTEGERS
    RULES FOR DIVISION
    ( -) / ( + ) = ( - )
    ( -) / ( - ) = ( + )
    ( + ) / ( + ) = ( + )
    (+ ) / ( - ) = ( -)
    AS MULTIPLICATION IN CASE OF DIVISION ALSO THE SIGN RULES ARE VERY IMPORTANT. THE NEGATIVE AND POSITIVE NUMBERS WILL BE VALUED AS PER THE ABOVE RULES.
