Solving Negative Number Word Problems

The video tutorial explains the difference between the coldest and warmest recorded temperatures on Earth, which are -128°F in Antarctica and 134°F in Death Valley, California. It uses a vertical number line to visualize these temperatures and demonstrates how to calculate the difference by subtracting a negative number, which is equivalent to adding its positive value. The tutorial concludes with the calculation of a 262°F difference between these extreme temperatures.
