1.To Find Square of a 3-Digit Number
Let the number be XYZ
a. Last digit = Last digit of Square (Z)
b. Second last digit = 2*Y*Z + any carryover from STEP 1
c. Third last digit 2*X*Z+ Square(Y) + any carryover from STEP 2
d. Fourth last digit is 2*X*Y + any carryover from STEP 3
e. Beginning of result will be Square(X) + any carryover from Step 4
Find the square of 431
a. Last digit = Last digit of Square (1) = 1
b. Second last digit = 2*3*1 + any carryover from STEP 1=6+0=6
c. Third last digit 2*4*1+ Square(3) + any carryover from STEP 2 = 8+9+0 = 17 i.e. 7 with carryover of 1
d. Fourth last digit is 2*4*3 + any carryover from STEP 3 = 24+1 = 25 i.e. 5 with carryover of 2
e. Beginning of result will be Square(4) + any carryover from Step 4 = 16+2 = 18
Thus, (431)² = 185761.
2.To find out the sum of 3-digit nos. formed with a set of given digits
This is given by (sum of digits) * (no. of digits-1)! * 1111…1 (i.e. based on the no. of digits)
Find the sum of all 3-digit nos. formed using the digits 2, 3, 5, 7 & 8.
Sum = (2+3+5+7+8) * (5-1)! * 11111 (since 5 digits are there)
= 25 * 24 * 11111
