Consider the sum,
-225+318
According to the rule for addition, subtract the absolute values of the addends when adding two numbers with opposite signs. The resultant has the same sign of the higher absolute value.
In the sum of -225+318, the higher absolute value has positive sign, so the resultant must have positive sign.
Therefore, the value of the expression -225+318 is positive.
