Step  1  :

 1.1     10 = 2•5

(10)^-2 = (2•5)^(-2) = (2)^(-2) • (5)^(-2)

Equation at the end of step  1  :

  1043     76
  ———— -  (—— • ((2)(-2)•(5)(-2)))
  1000     10

Step  2  :

            38
 Simplify   ——
            5 

Equation at the end of step  2  :

  1043     38
  ———— -  (—— • ((2)(-2)•(5)(-2)))
  1000     5 

Step  3  :

Multiplying exponents :

 3.1    5¹  multiplied by  5²   = 5^{(1 + 2)} = 5³

Dividing exponents :

 3.2    2¹   divided by   2²   = 2^{(1 - 2)} = 2^(-1) = ¹/_2¹ = ¹/₂

Equation at the end of step  3  :

  1043     19
  ———— -  ———
  1000    250

Step  4  :

            1043
 Simplify   ————
            1000

Equation at the end of step  4  :

  1043     19
  ———— -  ———
  1000    250

Step  5  :

Calculating the Least Common Multiple :

 5.1    Find the Least Common Multiple

      The left denominator is :       1000 

      The right denominator is :       250 

      Least Common Multiple:
      1000 

Calculating Multipliers :

 5.2    Calculate multipliers for the two fractions


    Denote the Least Common Multiple by  L.C.M 
    Denote the Left Multiplier by  Left_M 
    Denote the Right Multiplier by  Right_M 
    Denote the Left Deniminator by  L_Deno 
    Denote the Right Multiplier by  R_Deno 

   Left_M = L.C.M / L_Deno = 1

   Right_M = L.C.M / R_Deno = 4

Making Equivalent Fractions :

 5.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)²   and  (y²+y)/(y+1)³  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

   L. Mult. • L. Num.      1043
   ——————————————————  =   ————
         L.C.M             1000

   R. Mult. • R. Num.      19 • 4
   ——————————————————  =   ——————
         L.C.M              1000 

Adding fractions that have a common denominator :

 5.4       Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

 1043 - (19 • 4)      967
 ———————————————  =  ————
      1000           1000

Final result :

   967           
  ———— = 0.96700 
  1000
