Squaring a 2 digit number beginning with 1
1. Take a 2-digit number beginning with 1.
2. Square the second digit (keep the carry)___________X
3. Multiply the second digit by 2 and add the carry (keep the carry) _ X _
4. The first digit is one (plus the carry) X_________
Example:-
1. If the number is 16. square the second digit: 6x6 = 36________6
2. Multiply the second digit by 2 and add the carry: 2x6 + 3 = 15 _5_
3. The first digit is one plus the carry: 1 + 1=2 2_______
4. So 16 x 16 = 256.
See the pattern?
1. For 19x19, square the second digit:9x9 = 81 __1
2. Multiply the second digit by 2 and add the carry: 2x9 + 8 = 26 _6_
3. The first digit is one plus the carry: 1+2 = 3 3_______
4. So 19 x 19 = 361.
