1. is 1 a prime number or composite number? how do you know?
2. how do you know when you have found all the factors of a number?
3. define multiple.
4. define square number.
5. how do you know if a number is a square number or not?
pick 1 or as many as you like to answer. you so much

1. 1 is a composite number because 1 is not a product of 1.

2. To find the prime factorization of a number, divide it and all its factors until every remaining number is prime.

3. The result of multiplying a number by an number(not by a fraction).

Examples: 
• 12 is a multiple of 3, as 3 × 4 = 12
• 6 is a multiple of 3, as 3 × 2 = 6
• But 7 is NOT a multiple of 3

4. In math, a  square number or perfect square  is an number that is the square of an number; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3.     

5.You get a square number by multiplying a number by itself, so knowing the square numbers is a handy way to remember part of the multiplication table. Although you probably remember without help that 2x2 = 4, you may be sketchy on some of the higher numbers, such as 7x7 = 49. Knowing the square numbers gives you another way to etch that multiplication table forever into your brain..
The following figure shows the first few square numbers: 1, 4, 9, 16, and 25.From here, you can determine more square numbers:36, 49 ,64 . . . .Visual aids can help you find square numbers. The tastiest visual aids you’ll ever find are those little square cheese-flavored crackers. (You probably have a box sitting somewhere in the pantry. If not, saltine crackers or any other square food works just as well.) Shake a bunch out of a box and place the little squares together to make bigger squares, as shown in the above figure.

Hope this helps!
