Is it question 3? Can’t remember the question?
-
is 3
-
Me too!
We take 150-17=133
We take 100-5=95
common factors of 133 and 95: 1 and 19
so the number of neighbours is 19^^ -
Yea
-
19 neighbours.
-
Oh yes. I remembered. I got 19 too. But I was thinking if the answer can be 1 since it is also a common factor. Hehe.
-
The ticket question is $24.
-
Maybe we should compile a list of answers.
-
Is there one stamps or marble question?

Strongly agree with you nerdy math.
