the temperateure of Mars reaches 27 degree celsius during the day and -125 degree celsius at night. What is the average temperature?

can youhelp me do this problem i am not sure.

-125 + 27 = -98

-98 / 2 = -49

depends on the relative length of day and night, as well as the speed of heating/cooling.

Lots more info needed here.

thank you can you tell me a website where i can go online to practice additing integers having trouble. i understand adding subracting better than adding

You're welcome.

Of course! To find the average temperature, you need to add the two temperatures together and then divide by 2.

So, to calculate the average temperature on Mars, you would do:

(27°C + (-125°C)) / 2

First, let's add the two temperatures together:

27°C + (-125°C) = -98°C

Now, divide the sum by 2:

-98°C / 2 = -49°C

Therefore, the average temperature on Mars would be -49°C.
