00:00Here's a fast calculation square root trick you have to try.

00:03First, take the numbers 2, 8, and 9.

00:10When you add them together, you get 19.

00:13Now, subtract 2, and you end up with 17.

00:21That was really easy, wasn't it?

00:23Next, let's look at another set of numbers.

00:26Add 1, 9, and 6.

00:30Which equals 16.

00:33Subtract 2 again, and you get 14.

00:42Moving on, add 6 and 4 to get 10.

00:49Subtracting 2 from 10 leaves you with 8.

00:56Finally, consider 2 and 5.

01:01Adding these together gives you 7.

01:03Subtract 2, and the result is 5.

01:10Now, let's move on to cube root tricks.

01:12First, we have 1 plus 2 plus 5, which equals 8.

01:21Subtract 3, and you get 5.

01:25Next, we have 2 plus 1 plus 6, which equals 9.

01:35Subtract 3, and you get 6.

01:40These calculation tricks are incredibly easy.

01:43Let's put them into practice and finish the next equation using the methods we've just learned.

01:47To include,

02:09And now, let's move on.
