JANET SUMNER:

Hello, and welcome to Week two of Understanding numbers. See? I told you there wouldn't be any maths, just some numbers and a bit of science.

We'll start this week with a video about calculators. I don't know about you, but I just use the app on my phone. Later in the week, you'll learn about area, volumes, and density. And gradually work out what would happen to sea level if the Greenland ice sheet were to melt. Greenland hasn't always been covered in ice. In fact, it's only about 100,000 years old. That's 10 to the power of 5, for those of you who took scientific notation to heart last week. Did you know that just less than 80% of Greenland is covered in ice? Ooh, sorry! Percentages are coming up.

So let's get started, and I'll see you next week.
