The hosts of Fox News' morning show on Tuesday proved that many adults have poor math skills by failing a simple quiz from their own children in an epic way.

Fox & Friends hosts Steve Doocy, Gretchen Carlson and Brian Kilmeade noted that a recent study found that only about 5 percent of parents could help children with their math homework.

To find out if the study was true, the hosts used their own kids to quiz them on simple math questions.

Doocy started off well, answering the first question about multiplication correctly. Carlson literally scratched her head before picking wrong from the list of multiple-choice answers. Kilmeade declined to offer response.

The next question, however, did not go as well.

"Change 2.5 kilograms to grams," Carlson's daughter asked.

"Uh oh," Carlson grimaced.

"I'm going to say 'A'," Kilmeade offered.

"I'm going to say 'B' because I have no idea," Carlson said.

"I don't think the answer is there," Doocy shrugged. "A kilogram is a thousandth of a gram?"

After learning that the answer was 'C' -- 2,500 grams -- Kilmeade demanded a recount.

A question about finding 3 percent of $200,000 also stumped the trio. But in their defense, the correct answer was not offered in the list of choices.

"I'm confused," Carlson said. "Come on, it's 6,000!"

"There's nobody even helping us in the control room," Kilmeade complained. "During the Jeb Bush interview, I get all these helping from the control. I get nothing from them afterward because you guys don't know it either!"

"Does somebody have a calculator on their phone?" Carlson asked.
