"Billion," with a "B!" Way to go, team! Now we're thinking, "Could we go even faster?" So, a challenge for you: Can you help get us to 10 BILLION by this time next year? Try a problem Here's one to whet your appetite: How many problems would each of our 13 million students need to do per week to answer 8 billion more problems within the next year? (Round to the nearest whole number, and assume the number of students doesn't grow, though we're sure hoping it does!) ;;;Let's answer 8 billion more! Did you figure out our appetizer? Now try a problem and help us reach 10 billion.
