Adding 2 hot cubes and adding 4 cold cubes

How can we represent the cubes mathematically?

The mathmaster chef needed to decrease the temperature 8 degrees… He added some cubes and removed some cubes….

Our mathmaster chef’s assistants get confused.... which of these could decrease the temperature 5 degrees? Taking out 5 hot cubes Adding 5 cold cubes Taking out 5 cold cubes Adding 5 hot cubes

Our mathmaster chef’s assistants get confused.... which of these could increase the temperature 4 degrees? Taking out 4 hot cubes Adding 4 cold cubes Taking out 4 cold cubes Adding 4 hot cubes

What is the temperature of the pot below?

What are some ways his assistant decrease the temperature 3 degrees?

The mathmaster chef’s four assistants each increased the temperature of their pots 5 degrees in a different way…

Mathmaster chef told his assistant to decrease the temperature by removing 5 hot cubes…but there aren’t any cubes to remove! What can his assistant do?

Mathmaster Chef left these notes for his assistants. Can we tell what he wants us to do or do we need to ask him for more information? (- 3)

- 1 – (+2)

What does the Mathmaster chef want his assistant to do? 2 – (-2)

What does the Mathmaster chef want his assistant to do?

What does Mathmaster Chef want his assistant to do? - 1 – (- 2)

To decrease the temperature 8 degrees Mathmaster Chef… … added some cubes then removed some cubes. But he made a mistake and had to remove more cubes… What might he have done?
