Rounding is an aproximation. Find the most simple multiplication possible

Multiplication x2 is the most simple , after 1 multiplication

Use result. 2^ 5 = 32

So this means multiply 478 by 2 , five times

Duplicate in every step

So then

478x2 = 956

956x2= 1912

1912x2= 3824

3824x2= 7648

7648x2= 15296
