Here's a trick to calculate square numbers quickly. What's 24^2?
It's simpler than it looks at first glance: Go down four to the nearest easy number which is 20.
To balance it, go up four on the other number to 28. So the first calculation is 20 x 28. Two times 28 = 56, so add the zero and the answer is 560.
You're close. To get the final result, all you have to do is to add the square of the number you went up or down – in this case it was four, to get your answer: 576.

So, to summarise, 24 x 24 = (20 x 28) + (4 x 4), which is 576."

Take shortcuts whenever possible🤓

Multiplying numbers that end in zero is actually quite simple. It involves multiplying the other numbers together and then adding the zeros at the end. For instance, consider:

200 x 400

Step 1: Multiply the 2 times the 4

2 x 4 = 8

Step 2: Put all four of the zeros after the 8

80,000

200 x 400= 80,000

Practicing these fast math tricks can help both students and teachers improve their math skills and become secure in their knowledge of mathematics—and unafraid to work with numbers in the future.
