Maths Tricks ==> SQUARE OF ANY 2 DIGIT NUMBER

SQUARE OF ANY 2 DIGIT NUMBER

Let me explain this trick by taking examples
67^2 = [6^2][7^2]+2067 = 3649+840 = 4489

similarly
25^2 = [2^2][5^2]+2025 = 425+200 = 625

Take one more example
97^2 = [9^2][7^2]+2097 = 8149+1260 = 9409
Here [] is not an operation, it is only a separation between initial 2 and last 2 digits

EXAMPLE.
Here an extra case arises
Consider the following examples for that
91^2 = [9^2][1^2]+2091 = 8101+180 = 8281

SQUARE OF ANY 2 DIGIT NUMBER

Let me explain this trick by taking examples 67^2 = [6^2][7^2]+20*6*7 = 3649+840 = 4489

similarly 25^2 = [2^2][5^2]+20*2*5 = 425+200 = 625

Take one more example 97^2 = [9^2][7^2]+20*9*7 = 8149+1260 = 9409 Here [] is not an operation, it is only a separation between initial 2 and last 2 digits

EXAMPLE. Here an extra case arises Consider the following examples for that 91^2 = [9^2][1^2]+20*9*1 = 8101+180 = 8281
