Multiplication FIGURES IN TWO-FIGURE 5 ends

Here's my quick math tricks write quadratic double-digit multiplication
Ok step Notice

25 x 25 = 6 2 5
Step 1: after the number 2 is 3
Step 2: the product of 2 by 3 is 6
Step 3: Add the number 25 after 6

In the same way you can do multiples below

35 x 35 = 1225
45 x 45 = 2025
55 x 55 = 3025
65 x 65 = 4225
75 x 75 = 5625

and so on ...
