In Gaza, people are freezing in winter.  At one day the temperature was -2oF in the early morning and raised 4 degrees at noon  What was the temperature at none?

Answer = (1)

Correct Answer

(1) -2

Explanation

We will carefully read the problem looking for a key word or phrase.  Key words and phrases indicate what arithmetic operations should be used to solve the problem.

The phrase raised 4 degrees indicate addition.  With that in mind, we translate the words of the problem to numbers and symbols.

The temperature at none = -2 + 4

To find the sum, we will use the rule for adding two integers that have different signs.  First, we find the absolute values: |-2| = 2 and |4| = 4.

Subtract the smaller absolute value from the larger absolute value 4 - 2 = 2.  Since the positive number; 4, has the larger absolute value, the final answer is positive.

The temperature at none was 2oF.
