41.526+713.806= 755.332
755.332 - (a+135408) =245.132
755.332-245.132=a+135.408
755.332 - 245.132 - 135.408 = a
a=374.792
(51.432-b) = 150.100 - (113.826 - 39.712)
51.432 - b = 150.100 - (113.826 - 39.712)
51.432 - [150.100-(113.826-39.712)]= b
b=51.432 -(150.100-74114)
b=51.432-75.986
b= - 24.554
800.500 -625.912 = 174.588
174.588 + c - 17.590 = 357.539
174.588 + c = 357.539 + 17.590
c = 375.129 - 174.588
c = 200.541
