Lori was given the problem 2 x 10 x 4. Her work is shown below.
-First, Lori multiplied 2 x 10 = 20
-Then, Lori took the product from the first step and multiplied 20 x 4 = 80
-Finally, she added the 2 products: 20 + 80 = 100
-Her final answer was 100.
Is Lori’s final answer correct? Use words, a labeled diagram, and calculations to solve the problem correctly and explain Lori’s mistake.
Lori is incorrect. The correct answer for 2 x 10 x 4 is 80. Lori should have stopped after step two. There is no addition needed in this problem, so she did not need to add 20 and 80.
