what is the sum of the integers from - 190 to 191 inclusive ?
"sum / n = average . sum = ( average ) ( n ) average = a + b / 2 = 190 + 191 / 2 = 0.5 number of items ( n ) = b - a + 1 = 191 - ( - 190 ) + 1 = 195 + 191 = 382 . sum = average * n = 0.5 * 382 = 191 . answer is b"
divide(multiply(190, 191), const_4)
