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
Since 1+99=100. And 2+98=100 and 3+97=100 etc to 49+51=100 it's 49 of those plus 50 or 4,950. The sum of the first 99 whole numbers is 4,950
As 3844 ends in 4, its square root (if a whole number) will end in 2 or 8. √3844 = 62 so the unit digit is 2.
113.04 rounded to the nearest unit is 113. Take the last digit of the WHOLE number, in this case, the 3.
the unit digit is 4
Any digit in the tens or higher place has no influence on the answer. So it is the unit digit of 4*9*3*6 = unit digit of 6*3*6 = unit digit of 8*6 = 8
It is the unit's digit of the product of the unit's digits. For example, the units digit of 123456 * 4689 is simply the units digit of 6*9 = 54, which is 4.
18 numbers are there
To the right of the digit in the unit's column.
The unit's digit is 0. That is true for the product of the first n primes provided n>2.The unit's digit is 0. That is true for the product of the first n primes provided n>2.The unit's digit is 0.

Ten.
It is 1.
As 3844 ends in 4, its square root (if a whole number) will end in 2 or 8. √3844 = 62 so the unit digit is 2.
21, 51, 81, 91.
113.04 rounded to the nearest unit is 113. Take the last digit of the WHOLE number, in this case, the 3.
128 Look at the first digit to the right of the decimal point. It is 4. Since it is less than 5, round down to the nearest whole number.
the unit digit is 4
Any digit in the tens or higher place has no influence on the answer. So it is the unit digit of 4*9*3*6 = unit digit of 6*3*6 = unit digit of 8*6 = 8
It is the unit's digit of the product of the unit's digits. For example, the units digit of 123456 * 4689 is simply the units digit of 6*9 = 54, which is 4.
