Answer:

James is correct

Step-by-step explanation:

Given the expression wrote by a meteorologist as 78 + (-6), If James believes that this expression is the same as 78-6 then James is correct because if the parenthesis is expanded the product of the addition and the subtraction sign will produce a negative sign i.e + * - = -

78 + (-6) =  78 - 6 = 72

Based on the conclusion, we can say that James is correct in his reasoning
