There are infinitely many numbers between any two different numbers. To find a number exactly in the middle between two numbers, calculate the average. That is, add the two numbers, then divide the result by 2.

Even numbers can be matched up in two lines. Odd numbers have one left over.

Numbers were named after the number of angles they represented, and each angle represented a quantity. For example, the number one has one angle, number two two and so on. They have to be written with straight lines (not curved).

Coordinate planes

Typically a number is used to represent the exact amount of things you are counting. Numbers in telephone numbers actually don't count anything and were just a convenient way to categorize lines.

You model your equation on a number line to using a bar model.

A factor tree is very useful when identifying the prime factors of a number. You draw two lines off of it and write two numbers that multiply together to make that number. If one of the numbers cannot be divided any further, then circle it. That is a prime number. Draw two lines off of numbers that can be divided further, so you have multiple branches dividing off into certain numbers. Once all the numbers have been divided down, you are left with prime numbers which you can then multiply to get back to the original number.
