so-called turtle-head method.
so the multiplication, ignoring the decimal point for just a second, is 025000, or just 25000.
now, let's mind the decimal point, there are two decimals, two integers to the right-side of the dot, so therefore, our product must also have two decimals, two digits to the right-side too.
250.00, and we can write it as just 250.
