## Welcome to the Math Section

### Welcome to the SSC's Mathematics Section

#### Here you can find dozens of resources to help you get through your math class. We have a collection of general math resources on this page, as well as pages dedicated to quantitative reasoning, statistics, and trigonometry. ## Math Resources When evaluating mathematical expressions, be sure to follow the order of operations:

1) G: Groupings. These include parentheses, brackets, and braces.
2) E: Exponents. This includes roots and radicals.
3) M and D: Multiplication or Division. These both have the same "weight" so when you get to this step do whichever operation comes first when working from left to right.
4) A and S: Addition or Subtraction. These both have the same "weight" so when you get to this step do whichever operation comes first when working from left to right.

## Types of numbers (and their symbols)

The main types of numbers are:

• Natural Numbers (N), (also called positive integers, counting numbers, or natural numbers); They are the numbers {1, 2, 3, 4, 5, …}
• Whole Numbers (W). This is the set of  natural numbers, plus zero, i.e., {0, 1, 2, 3, 4, 5, …}.
• Integers (Z). This is the set of all whole numbers plus all the negatives (or opposites) of the natural numbers, i.e., {… , ⁻2, ⁻1, 0, 1, 2, …}
• Rational numbers (Q). This is all the fractions where the top and bottom numbers are integers; e.g., 1/2, 3/4, 7/2, ⁻4/3, 4/1 [Note: The denominator cannot be 0, but the numerator can be].
• Real numbers (R), (also called measuring numbers or measurement numbers). This includes all numbers that can be written as a decimal. This includes fractions written in decimal form e.g., 0.5, 0.75 2.35, ⁻0.073, 0.3333, or 2.142857. It also includes all the irrational numbers such as π, √2 etc. Every real number corresponds to a point on the number line. ## Math Tutoring 101

##### It's important that your math grade reflects your personal effort and abilities, which can sometimes be more difficult when all your homework, tests, and quizzes are online. Student Success Commons tutors are here to help you, but in a way that ensures your work is your own. If you seek help from a SSC math tutor, please first understand what you can and can't expect.
