How do i do two by two multiplication

Easy its just like adding 2 by 2 all your doing is this for example 22
                                                                                                 X  44
                                                                                                     88

You can us a calculator or u can memorize them 
the way I learned how to multiply is by memorizing them

but basically
2x2=4
2x3=6
2x4=8
2x5=10
2x6=12
 

It says in the questions that it is 6.5?
