and the bot is wrong
None of the given expressions accurately show what the temperature was at the start of the day.
To find the temperature at the start of the day, we need to subtract the total increase in temperature from the temperature at the end of the day.
The expression that shows what the temperature was at the start of the day is:
64 - 8 - 4
To find the temperature at the start of the day, we need to subtract the total increase in temperature from the end of the day temperature.
First, let's find the total increase in temperature. The temperature increased by 8 degrees and then increased again by 4 degrees. So, the total increase is 8 + 4 = 12 degrees.
Now, to find the temperature at the start of the day, we subtract the total increase from the end of the day temperature:
64 - 12 = 52 degrees.
Therefore, the correct expression that shows what the temperature was at the start of the day is: 64 - 8 - 4.
