My kids know a nonillion!

Curious kids will have a blast and impress their teachers after playing with this app. Most adults can't name numbers after 999 trillion. Or even begin wrapping their heads around what big numbers mean or represent. I love this stuff. good job.

Number dictation is awesome

Great fun. Very cool to visualize such big numbers, see how big they really are, and read examples about what they represent... Recommended for everybody. We need to be prepared to understand larger worldwide debt numbers! What comes after trillions? Ha!
