IN WHOLE NUMBER FIRST DIGIT IS 0 SO THAT WE HAVE TO SUM 1-98 NUMBERS
:-SUM OF 1-10 IS 55 SO IN SUM OF EACH 11-20,21-30......THE UNIT DIGIT WILL COME 5 SO FOR THAT WE MULTIPLY
5*9+1+2+3+4+5+6+7+8
AFTER THIS CALCULATION WE GOT 1 AS A UNIT DIGIT NUMBER

JordanTo 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.

Oh, dude, you want to know the unit's digits of the product of the first 21 prime numbers? Well, let me casually tell you that the unit's digit of a product depends on the unit's digits of the numbers being multiplied. Since the unit's digit of all prime numbers greater than 5 is either 1, 3, 7, or 9, the product of the first 21 prime numbers will end in a unit's digit that is a result of multiplying these digits together. Cool, right?
