OoO (Ghost). What does the OoO mean?
Order of Operations.

What is a multiple?
SKIP COUNTING. A multiple is a product of factors.
300
Why are 30 and 24 the worst first moves in the Factor Game?
Because the sum of the proper factors of 24 and 30 are greater than the number. In other words, your opponent gets more points then you do in the first turn.

What is the LCM?
LCM = Least Common Multiple

30 is an abundant number. What does this mean? (Hint: think of its factors and the Factor Game)
The sum of the factors of 30 are greater than 30. In other words, your opponent earns more points than you.

What is the GCF between 24, 36, and 18? What is the LCM between 24, 36 and 18?
GCF = 6, LCM = 72
500
We know 2 x 2 gives us 4. Is there any other number that has the same prime factorization 2 x 2
No. It is impossible for another number to have the same factorization because that would say that 4 = that other number.

Why is PEMDAS not considered a strategy? What should you put instead?
PEMDAS is a mnemonic. The strategy is called "Order of Operations".
500
What is the Order of Operations?
The order that say which operations comes first in an expression.
