But it tells us that the temperature of, um, fluid decreased negative six degrees per hour for 12 hours. So he wants to know what sign number gives us the total temperature change. So we have to do is multiply negative. Six times 12 and so negative. Six times 12 is gonna be a negative 772 uh, degrees. I was the temperature change. Thank you.
