Answers Update

Alright, we've been getting a lot of comments that the math and reading answers aren't working.
The math answers should work, you're probably not clicking on the right thing. For example, if I start with the bullet 10,000 BCE to CE, when you first open the Math Timeline, look down at the bottom of the screen where you see the 5 time periods, and choose the one I tell you to. In this example, choose 10,000 BCE to CE. Then when you choose a time period, you should see 4 more tabs to the right, Science, Geography, Culture and Career. After the first bullet 10,000 BCE to CE, I put another bullet after it that could be any one of these 4 tabs. For example, I could Science as another bullet after the 10,000 BCE to CE bullet. then I put the answers for that tab under that, and repeat for every time period. Please comment if you don't understand this process.
We will look into the reading answers, however, and you should see a change in them a few days from now.
Happy Mother's Day!
