table_5: balance december 31 2008 the deductions during period 2014disposition and retirements of property of $ 846258 is -11144 ( 11144 ) ;
table_8: balance december 31 2008 the deductions during period 2014disposition and retirements of property of $ 846258 is -21796 ( 21796 ) ;
Reasoning Steps:
Step: add2-1(11869, 11144) = 23013
Step: add2-2(#0, 21796) = 44809
Step: divide2-3(#1, const_3) = 14936.33
Program:
add(11869, 11144), add(#0, 21796), divide(#1, const_3)
Program (Nested):
divide(add(add(11869, 11144), 21796), const_3)
