Step 1: 2 * 3 = 6 (Write 6 which is the single digit number)
Step 2: 6 * 3 + 2 * 4 = 26 (Write 6 and 2 is carried over to the next step)
Step 3: 6 * 4 + 2 (Carried Over) = 26 (Write 26 as this is the last step).
2666 is the answer.

100 -86 = 14, 100 -93 = 7
14 * 7 = 98 (last two digits)
93-14= 86-7 =79
Therefore, the correct answer is 7998

Step 1: 1 * 7 = 07 (Write 07).
Step 2: 1 * 2 + 5 * 7 + 2 (Carried Over) = 37 (Write 7 and 3 is carried over to the next step)
Step 3: 5 * 2 + 3 (Carried Over) = 13 (Write 13 because this is the last step)
1377 is the answer.

(112) ² = 112 + 12 | (12) ² = 144 | (carry 4)44 = 12544

100 -89 = 11, 100 -109 = -9
11 * -9 = -99 (100-99=01) (last two digits) (1 borrowed)
109-11-= 89+9 =98 -1 (borrowed) = 97
Therefore, the correct answer is 9701

Step 1: 2 * 7 = 14 (Write 4 and 1 is carried over to the next step)
Step 2: 7 * 7 + 2 × 4 + 1 (Carried Over) = 58 (Write 8 and 5 is carried over to the next step)
Step 3: 7 * 4 + 5 (Carried Over) = 33 (Write 27 because this is the last step)
3384 is the answer.

n this case, we can take 50, which is a sub multiple of 100 or a multiple of 10 and proceed as follows: 50 -41 = 9, 50 -43 = 7
9 * 7 = 63 (last two digits)
41-7= 43-9 = 34/2 = 17
Since 50 = 100/2, we divide the left hand side number also by 2 while retaining the right hand side. Therefore, the answer will be 2068.

55² ⇒ (5 * 6), 25 = 3025

100 -87 = 13, 100 -93 = 7
13 * 7 = 91 (last two digits)
93-13= 87-7 = 80
Therefore, the correct answer is 8091

(82) ² = 82 – 18 | (18) ² = 6724
