A research team sent to the rain forest found an important message from a missing scientist. In the message, the scientist talked about a multiplication problem she was working on. Unfortunately, only the answer to the problem was readable. The scientist left evidence that the two numbers she multiplied together use the digits 2-6 only once. The research team discovered an answer of 8704. What was the problem? You MAY use a calculator, however, I need to see all the evidence of your thinking and a list of the equations you tried, with an explanation of why you chose those numbers.

Everyone at the party was given 10 tickets. You used one ticket each time you played a game. John wanted to play a game where you could win a soccer ball. Two green blocks, one white block, and red block were placed in a bag. If you pulled out two green blocks, you won a soccer ball. If you pulled out any other combination of blocks, you won a piece of gum that looked like a soccer ball. John told his friend Jen that he would play this game because he knew he could win. Jen suggested that he might want to look at the other games first, because she knew John did not like to chew gum! What advice would YOU give John? Why? <span style="color: #0012ff; display: block; font-family: 'Comic Sans MS',cursive; font-size: 120%; text-align: left;">
