what number is obtained by adding the units digits of 734 ^ 99 and 347 ^ 82 ?
"the units digit of 734 ^ 99 is 4 because 4 raised to the power of an odd integer ends in 4 . the units digit of 347 ^ 82 is 9 because powers of 7 end in 7 , 9 , 3 , or 1 cyclically . since 82 is in the form 4 n + 2 , the units digit is 9 . then 4 + 9 = 13 . the answer is d ."
subtract(subtract(99, 82), divide(99, add(const_1, const_10)))
