Try squaring a 3 digit even no or a 4 digit even no. mentally. Oh yeah it’s hard. But what if we make it easy. What if for squaring a 3 digit no. you just need to multiply a 3 digit no with a two digit. Yeah! it would be far more easy. By following the given steps you can easily do so. Here you go : –
- Choose a no.
- Divide the no by 2.
Thus 124 / 2 = 62
- Multiply the original no by the quotient you got.
Thus 124 * 62 = 7688
- Now the final step is to multiply the product by 2.
Thus the desired answer is 7688 * 2 = 15376Enjoy your squaring guys 🙂 😀
