3rd grade math

16 1/2 x 33 = is it 792

16*2+1 = 33
so 16 1/2 = 33/2
so
33*33/2 = 544.5 
I do not think that is third grade math so suspect a typo.

No.
One way to solve this problem is like this:
(1/2) * (33/1) = 33/2 = 16 1/2
16 * 33 = 528
528 + 16 1/2 = 544 1/2
You could also use 16.5 for 16 1/2 and multiply. The answer is the same: 544.5 
(16 1/2)x33= 16*33+(1/2)*33=
528+33/2=
528+(32+1)/2=
528+16+(1/2)=544 1/2 
528+(32+1)/2= 528+(32/2)+(1/2)528+16+(1/2)=544 1/2

528+(32+1)/2= 528+(32/2)+(1/2)=528+16+(1/2)=544 1/2
