Factors and divisibility

The  exercise appears under the Early math Math Mission. This exercise practices the relationship between products and their factors (spoiler: a product is divisible by its factors).

Types of problems
There are two types of problems in this exercise:
 * 1) Which of the following monomials are divisible by ___ ?: This problem has four monomials and user is asked to find which ones are divisible by ___.
 * 2) Who is correct?: This problem pretends that a teacher writes a problem on the board and two students solve them. User is asked to find which student(s) are correct

Strategies
Knowledge of subtracting small numbers within 100 are encouraged to ensure success while doing this exercise.
 * 1) When two or more monomials with integer coefficients are multiplied, we say that this product is divisible by each of these monomials. Additionally, we call each of these monomials a factor of the product.

Real-life Applications

 * 1) Problems like this will appear on standardized tests, like the SATs and ACTs.
