The Chef’s Hot and Cold Cubes

In a far-off place,

During the cooking process, they frequently had to change the temperature of the cauldron in order to bring out the flavors and cook the food to perfection.

What are hot cubes and cold cubes?

The cold cubes were similar to ice cubes except that they didn’t melt, and the hot cubes were similar to charcoal briquettes, except they didn’t lose their heat.

How does each cube affect the temperature? If the number of cold cubes in the cauldron was the same as the number of hot cubes, the temperature of the cauldron was 0 degrees on their temperature scale. For each hot cube that was put in the cauldron, the temperature went up one degree; for each hot cube removed, the temperature went down one degree.

How does each cube affect the temperature? Similarly, each cold cube put in lowered the temperature one degree and each cold cube removed raised it one degree. The chefs used positive and negative numbers to keep track of their changes they were making to the temperature.

Fill in the blank

Similarly, if they added 3 hot cubes and then removed 2 cold cubes, the combined result would be to raise the temperature 5 degrees. In that case, they would write (+3) - (-2) = +5 When subtracting integers, we add the opposite of the second integer to get the result. Therefore, we can also say (+3) + (+2) = +5.
