find the sum of first 89 odd numbers
"explanation : n 2 = 892 = 7921 answer : option a"
add(divide(divide(89, divide(divide(divide(divide(divide(89, const_2), const_2), const_2), const_2), const_2)), const_2), add(const_1, sqrt(divide(divide(89, divide(divide(divide(divide(divide(89, const_2), const_2), const_2), const_2), const_2)), const_2))))
