Squaring Two-Digit Numbers Techniques

In this video, Akash teaches a simple trick to square any two-digit number mentally. The method involves dividing the solution into three parts: the square of the first digit, the product of the two digits multiplied by two, and the square of the last digit. Akash demonstrates this technique with examples of squaring 21, 32, 67, and 84, explaining the process of carrying over digits when necessary. The video concludes with a homework assignment to practice the trick with other numbers.

What is the first step in squaring a two-digit number using the trick explained in the video?

• Square the last digit of the number.

• Square the first digit of the number.

• Multiply the two digits together.

• Add the two digits together.
