Answer:
7218°C
Explanation:
difference between the two numbers 7000 and -218 is
7000-(-218) = 7000+218 = 7218
(NOTE: When conditions like this arise, when two minus (-) sign come together, replace the two minus with a plus sign and open the brackets. When two plus sign occurs together, do not replace it with a minus sign, just replace with a single plus sign)
