NUMBER SYSTEM CHAPTER 1

NUMBER SYSTEMS


  In number system first we explain the B O D M A S theory
       
  In simplifying an expression the following order must be      adhered to
                                 
                                B => Brackets                          () {} []

                                O = > Of

                                D => Division

                                M => Multification                      *

                                A => Addition                            +

                                S => subtraction                        -

Example1:
         
             2184 * (40+95-23) = ?

Ans: in the above example according to BODMAS rule first we solve the bracket the bracket ans is 112 next we solve the multification then the answer is “244608”.

Example2:
            
           95/19*4(24+96-50)

Ans: here (24+96-50)=70
          95/19 =5
      Therefore = 5*4(70)
                    = 1400
          Ans is 95/19*4(24+96-50) =1400.


Example3:

             2/7*5/6*3/8=?

Ans:    here we calculating the ans is “5/56”.


Example 4:

               7/8 of 448 + 6/7 of3374 =?

Ans: here we know  of == ‘*’   calculation is
           7/8*448 =   7*56 =   392
           6/7*3374 = 6*482 = 2892
           Ans =392+2892=3284.


Example 5:

            9of8/18(21*7+54+66)

Ans:
       (21*7+54+66) = 267
       9of8 = 72  è 72/18= 4 then
          4*267=1068
       9of8/18(21*7+54+65)=1068
