Remember when math teachers told you that one day you'd need to remember how to solve complex equations involving fractions? Today is that day.
Follow along with this BuzzFeed video -- Adults Try 5th Grade Math -- to see if you can solve math problems like 66.51 x 98.65 = ? and 4321.4 / 82 = ? without using a calculator.
Good luck. Because these adults weren't as fast with the answers as you might expect. As the video goes on, the math gets more complicated and the hosts get more frustrated.
"Patience is the key to long division," one adult in the video says.
Says another exasperated adult who still didn't quite get the correct answer, "As far as I'm concerned, that's rocket science."
Perhaps we adults should brush up on our math skills by watching actress Danica McKellar's educational show "" on the Nerdist Channel? Or maybe we need a good dose of to jolt our math memories? Either way, it might be a good time to download a or two to help remind us why skills like these are important.
