Question

Uma used the expanded algorithm to solve 62 x 13. She wrote 13 x 62= 6 + 2 + 180 +60=248. What did she do wrong? Explain what partial products Uma ahould have added to find the correct product.

Answer 1

62 x 13 = 6+20+180+600=806
She didn't multiply by the 1 in 13 correctly.

Hope this helps :)

Answer 2

She did not put the six as 60 she wrote it as 6
