Excel IF/AND/OR/NOT Functions

Hi guys, 

I need some help in writing a formula. 

basically, in cell G43, i wanna say if cell B43 is less than 40 to display the number 0, if B43 is less than 20 to display the number 1 or if B43 is less than 10 to display the number 2. 

is it possible to get this all into one formula?
