(CNN) While addressing a question from CNN's Anderson Cooper on funding free tuition for college, Massachusetts Sen. Elizabeth Warren touted her wealth tax proposal.

"If we put that 2 cent wealth tax in place on the 75,000 largest fortunes in this country," she said, "we can do universal child care for every baby 0 to 5, universal pre-K, universal college and knock back the student loan debt burden for 95% of our students and still have nearly a trillion dollars left over."

Facts first: According to studies commissioned by her campaign, the math might work. It also might not. Other estimates place the total revenue from the tax plan far lower and there are several procedural problems with the proposal, including its legality.

According to an analysis by economists Emmanuel Saez and Gabriel Zucman who worked with Warren on the plan, the wealth tax would pull $2.75 trillion into government coffers over 10 years. In a blog post , citing expert analysis, Warren wrote that her universal college plan would cost $1.25 trillion over a decade.

Mark Zandi, chief economist at Moody's Analytics who authored a study -- which was commissioned but not paid for by the Warren campaign -- on Warren's universal child care told CNN the plan would cost $700 billion over 10 years after accounting for the boost it would provide the economy.
