Question

The temperature started at 89°F. If the temperature went 6°F and down 12°F, what is the temperature difference relative to the high temperature?

Answer 1

Assumption: up `6^0" and down "12^0`

A reduction of `6^0`F. So the change is `-6^0`

Explanation:

`color(blue)("Mathematically how does this work?")`

The first change is: `" "89+6 = 95`
The second change is `" "95-12 = 83`

The starting point was 89 and it ended up at 83

So its final state in comparison to initial condition is

`color(green)("Start state")" to "color(brown)("end state")`
`" "color(green)(89)" to "color(brown)(83) -> " a reduction of "6^0`
