Question

The temperature on the side of a space shuttle that faces the sun is +250°C. The temperature on the shaded side is -130°C. What is the difference between these temperatures?

Please explain the answer

Answer 1

380º

Explanation:

Since the shaded side is in the negative and the sun side is positive and you're trying to find the difference between them, first you try to get the negative number to be positive. So add 130 to -130 to get 0. Then add another 250º to equal the two amounts. Now since they are equal, add the numbers that you used to get the two numbers to be the same: 130+250 = 380
