Distributive Property 

Its when you multiply the number outside of the parentheses (aka a coefficient) by what is inside of the parentheses.*

 *Distribute first, then add -- PEMDAS (we will learn this later)

A prime number 

(Bonus point answer: 2,3,5)

300

Identify the composite numbers in this list 

1,4,6,9,11,15

What is the value of the 100,000ths place?

1,809,322

800,000

While the digit 8 is in the 100,000ths place, the value is 800,000

500

Please round this to the nearest 100ths

783,098

783,100

This is asking for the entire number to be rounded, not just a single place value. So you need to include the whole number given, not just "100".
