What children learn in Level 11

Big numbers are made of hundreds, tens, and ones.
2 hundreds is 200. 4 tens is 40. 3 ones is 3. Together they make 243!
Each digit has its own place. The 2 is in the hundreds place, so it's worth 200, not 2.
What about 305? It has 3 hundreds, no tens, and 5 ones. The zero holds the tens place, so the 3 stays in the hundreds.
Your turn! Use the plus and minus buttons to build 132.
1 hundred, 3 tens, and 2 ones makes 132. You built it!
