Below are two expressions, the only difference being the presence or absence of parentheses. expression 1:expression 2:4 2×(3 4)×(5−2)4 2×3 4×5−2 calculate the difference between the two expressions; that is, evaluate both expressions then subtract one value from the other value.
What we are going to do is develop both expressions separately. Expression 1: 42 * (34) * (5-2) 1428 * (5-2) 4284 Expression 2: 42 * 34 * 5-2 7140-2 7138 The difference between both expressions is: 7138-4284 = 2854 answer: the difference between the two expressions is 2854
