Yes she would be right and that is a smart short cut
no because 3 times 24 actually equals 72 she forgot to multiply the 2 tens by 3 if she would've done that the answer would be 7 tens and 2 ones :-)
Cindy's approach to multiplying 3 times 24 demonstrates the use of the distributive property, allowing her to break down the problem into manageable parts. By calculating 3 times 20 and 3 times 4 separately and then adding them together, she finds the correct answer of 72. This shows the importance of understanding multiplication as a sum of products.
