Not really. 62 x 7.38 = 457.56 must have 2 sig figs, which means 0 decimals. When we end up with 454.51 remember, it has to have 0 decimals (subtraction!) + the 2 sig figs from 457.56 = 450. Perhaps you rounded 457.56 to 458? We cannot round twice.

I like the video. First problem, shouldn't it have been rounded to 39.2? 8.2234 (3SF) X 4.763 (4SG) = 39.168 (Not 39.1168)

Hi Chris, thanks for commenting! You are totally right, I added an extra one in my problem on the board. Dang it! The answer should round to 39.2. Nice catch, we will try to re-upload mentioning the correction.
