Friends!
Continue to study math.
To bring up the square of the numbers 25, 35, 45, 55, 65, 75, 85, 95 it is necessary: as a result, at the end of the record number 25, and in front, the number that is the product of the first digit of the number, which we bring to a square in a digit, which goes after him.
For example: 65x65 = 6x7 = 42, and at the end write 25, that is, 65x65 = 4225.

Друзі!
Продовжуємо вивчати математику.
Щоб піднести до квадрату числа 25, 35, 45, 55, 65, 75, 85, 95 потрібно: в результаті в кінці записати число 25, а попереду, число, яке є добутком першої цифри числа, яке ми підносимо до квадрату на цифру, яка йде за ним.
Наприклад: 65х65=6х7=42, а в кінці записуємо 25, тобто 65х65=4225.
Had to check it with a calculator, not trusting my math, and it worked 👍😊 thank you for the math tip!
