The lowest recorded temperature in Sweden is -38 degrees and the lowest

recorded temperature in Russia is

-68 degrees. How much higher is the

low temperature in Sweden than the

low temperature in Russia.

-68 + -38 = -106 degrees.

Did I solve this right?

why did you ADD the two temperatures, when the question was to fing the difference?

Whenever you are not sure which operation to perform, reduce the problem to a simpler case.

for example, if you are 14 and your sister is 9, and somebody asks how much older you are than your sister, what would you do?

so for the temperature: -38º - (-68º) = 30º
