Can you explain this multiplication game? It's not clear to me...?

We Answered:

ON the answer card are the answers to all the possible multiplication combinations using the numbers 0-12. The child should pick up a question card and then point to the appropriate answer on the answer card. The answers are not in order, so the adult has to know the answers on his/her own. good luck :D

Group Theory :(?

We Answered:

the mod means you take the remainder, so for example 3 + 2 mod 4 = 1, since 3+2 = 5, and the remainder when you divide 5 by 4 is 1. similarly, 3*2 mod 4 = 2.

when it says construct a table, it means to make a grid that shows what happens when you add/multiply every pair of elements. I'll do the first one to illustrate.

....0 1 2 3
----------------
0 | 0 1 2 3
1 | 1 2 3 0
2 | 2 3 0 1
3 | 3 0 1 2
