What is sixteen times 8B3 ?

A good answer might be:

8B30

Shifting by one Place in Base Sixteen

Adding a 0 to the end of an integer written in base sixteen multiplies the integer by sixteen. To multiply an integer by sixteenN, add N zeros on the right: 

8B3 × 103 = 8B3000      (Here 10 means sixteen.)

Erasing a digit on the right divides an integer by sixteen (integer division). So 8B3 div sixteen   =   8B (with a remainder of 3).
