Given the expression:
2×(6+7); this means the multiplication of the previous sum between 6 and 7:
2 x (6 + 7) = 2 x 13 = 26
On the other hand, the expression:
2×6+7, refers to the multiplication between 2 and 6 and, the subsequent sum of 7:
2×6+7 = 12 + 7 = 19. Word expression: "7 more than the product of 2 and 6"
