Question

a temperature recorded in antarctica was - 77°f. the temperature recorded in the sahara desert was 134°f. how many degrees warmer is 134°f than - 77°f?

Explanation:

Step1: Identify the operation

We need to find the difference between two temperatures, so we use subtraction.
$134-(- 77)$

Step2: Apply the rule of subtracting a negative number

Subtracting a negative number is the same as adding its positive counterpart. So $134-(-77)=134 + 77$.
$134+77 = 211$

Answer:

$211^{\circ}F$
