Liam used an array to show how to find the product of 347 and 56. He first multiplies 50 by 300 and gets 1,500. When Liam multiplies 50 X 40, the product should be 2,000, and when he mulitipies 50 X 7 he gets 350. Did Liam correctly multiply the first set of numbers? If not, what should he fix.
No. His first partial product should be 15,000.
