ok how did you know how to subtract

  • misssunshinexxoxo
When you see this problem just simply subtract

-45 - 71 key term "change" means subtract
misssunshinexxoxo
  • misssunshinexxoxo
is that 71 a negative?
misssunshinexxoxo
  • misssunshinexxoxo
Answer is 26

\[-46 - -71 = 26 F\]

Change means subtract
misssunshinexxoxo
  • misssunshinexxoxo
If that 71 is negative your answer is 26

Don't let temperature intimidate the question; if you see change means subtract, increase means add and decrease is subtract

Are you sure it's 26F? :) @misssunshinexxoxo

what
Astrophysics

I'm asking are you certain it's 26 F?
Astrophysics

Temperature is not exactly like normal math...if I said it was -50F but it was -12F earlier, what is temperature difference?
Astrophysics
  • Astrophysics
Well it's normal math but you get what i mean Xd

im not the one who said it idk thats why i asked the question

(-71°F) - (-45°F) = (-71+45) °F = should be negative as it is getting colder
Astrophysics
  • Astrophysics
Haha, well since it's asking what is the change in temperature from -45°F to - 71°F, notice that it's going from -41 F -> -71 F so you have to subtract -71 F from - 45 F and that will be the difference between the temperature.
Astrophysics
  • Astrophysics
Or yes, exactly what UnkleRhaukus said

okay guys the war is over
Astrophysics

Lol, there's no war, I'm just trying to get you to understand the concept

"change" symbolizes subtraction
UnkleRhaukus
  • UnkleRhaukus
change in \(x\) is \[x_\text{final} - x_\text{initial} \] if you get the order wrong, you'll get the answer wrong
Astrophysics
  • Astrophysics
Yes! Change in temperature therefore is represented as such \[\Delta T = T_f - T_i\]
