Explain why using either compatible numbers or rounding as a method for estimation would be the same for 32*695?

The question here is why using either compatible numbers or rounding as a method for estimation would be the same?

Well, we use rounding as a method of estimation to get a solution in a certain equation faster yet the same.

For example, in the given equation we have 32 x 695

=> Instead of 32, we can use 30

=> instead of 695, we can use 700

=> 30 x 700

=> the answer is 21 000

Now, let’s multiply the exact number

=> 32 * 695

=> 22 240

Not, really exact yet close.

That’s how estimation works.
