Explanation Result used: Addition of a positive number and a negative number: “If the numbers have the same absolute values, the answer is 0. If the numbers have different absolute values, subtract the smaller absolute value from the larger. If the positive number has the greater absolute value, the answer is positive. If the negative number has the greater absolute value, the answer is negative”. Calculation: Consider the expression − 3 + 27 . Take the absolute value of the numbers − 3 and 27, which is 3 and 27
