SteveTo find the unit digit in the sum of the first 99 whole numbers, we can use the formula for the sum of an arithmetic series: n/2 * (first term + last term), where n is the number of terms. In this case, n = 99, the first term is 1, and the last term is 99. Plugging these values into the formula gives us 99/2 * (1 + 99) = 4950. The unit digit in 4950 is 0.
