Because if n is an odd number, n/2 will be a value with decimal points but the example in the question shows that the question wants sums of integers. The example in the question shows that integers are added to the desired sum but not values with decimal points added to the desired sum.

The example in the question shows that each integer to be added to the sum is the result of every n/2 rounded down (to the nearest integer which is smaller than the n/2 value which has decimal points). Math.floor() rounds a number with decimal points down (to the nearest integer which is smaller than the n/2 value which has decimal points).

Thanks for the solution. I have learnt something new (can simply pass 'inputString' into the argument of parseInt without a reference to the index of the age number). Thanks so much!!

That's brilliant!!
