Reasoning Steps:
Step: minus2-1(169.61, 163.63) = 5.98
Step: divide2-2(#0, 163.63) = 3.7%
Step: minus2-3(144.41, 169.61) = -14.9%
Step: add2-4(#1, #2) = -0.11199999999999999
Step: divide0-0(#3, const_2) = -5.6%
Program:
subtract(169.61, 163.63), divide(#0, 163.63), subtract(144.41, 169.61), add(#1, #2), divide(#3, const_2)
Program (Nested):
divide(add(divide(subtract(169.61, 163.63), 163.63), subtract(144.41, 169.61)), const_2)
