target range of the product in the table.
- Take 4 cards from the top of the
- Use the cards to try to form 2
numbers whose product falls within the target range. Do not
use a calculator. You need not use all 4 cards. A
number may not begin with 0.
- Multiply the 2 numbers on your
calculator to determine whether the product falls within the
target range. If it does, you have hit the bull's-eye and
