Answer:

Explanation:
Given : In the Sahara Desert one day it was 136°F.
In the Gobi Desert a temperature of -50°F was recorded.
Clearly , 136°F> -50°F
Then, the difference between these two temperatures will be :-
![136^(\circ)F-(-50)^(\circ)F\\\\=(136+50)^(\circ)F\ \ [\because \text{Product two neagtive sign is positive]}\\\\=186^(\circ)F](https://img.qammunity.org/2016/formulas/mathematics/middle-school/nw68rmq5y8f5twv32ige5foruxn9nsy33k.png)
Hence, the difference between these two temperatures =
