Question

The current temperature is -7°C. The high temperature yesterday was as many degrees above 0°C as the current temperature is below 0°C. Which expression could be used to find the number of degrees between the current temperature and yesterday‘s high temperature

Answer 1

`Number \ of \ degrees=7-(-7)=14^(\textdegree)C`

Explanation:

Current temperature is
`7^(\textdegree)C` below
`0^(\textdegree)C`.

So yesterday hight temperature will be
`7^(\textdegree)` above
`0^(\textdegree)`.

Yesterday high temperature =
`0+7=7^(\textdegree)C`

Number of degrees between current and yesterday high temperature
`=7-(-7)=14^(\textdegree)C`
