The record high temperature for Massachusetts is 109 degrees Fahrenheit. The record low is -20 degrees Fahrenheit. What is the difference between high and low?

1. Break Down the Problem

To find the difference between the high and low temperatures, we need to subtract the low temperature from the high temperature.

2. Relevant Concepts

The relevant formula to calculate the difference is: $\text{Difference} = \text{High Temperature} - \text{Low Temperature}$

3. Analysis and Detail

Given:

• High Temperature = 109°F
• Low Temperature = -20°F

Calculating the difference: $\text{Difference} = 109 - (-20) = 109 + 20$ $\text{Difference} = 129$

4. Verify and Summarize

The calculations are verified as the low temperature is subtracted from the high temperature, and adding the negative value leads us to correctly find the positive difference.

Final Answer

The difference between the high and low temperatures in Massachusetts is 129 degrees Fahrenheit.
