  1. Where is the times sign? I truly think it’s missing.

    • The times sign is left out on purpose (for now). It gets introduced in a later lesson in Ray’s. This is by design. The idea is to make sure the student masters the mental arithmetic operations first before bringing in the abstract symbols that we adults take for granted and are so used to seeing. It’s coming!
