Basically only the units digit has to be found so find the square of the units digit of both number and keep adding Like 2 give a 4 at its units place 5 gives a 5 at its units place 4+5=9 9 gives a 1 at its units place 1+5=6 6 gives a 6 at its units place 6+1=7 7 gives 9 at its units place 9+6=5 Only units digit required 5 gives a 5 at its units place 5+9=4 4 gives a 6 at its units place 6+5=1 1 is at the units place for the tenth observation therefore 1 is the remainder for the tenth observation divided by ten
