MAT-130 at Southern New Hampshire University is a three-credit mathematics course designed, in the catalog's words, to prepare students for other core and major courses and to support decisions in life after graduation.
Topics are the mathematics of finance, probability and counting, descriptive statistics and basic linear regression.
Students often find it manageable in pieces but demanding in volume. Each unit has its own formulas and vocabulary, so the skill is knowing which tool a word problem needs and setting it up cleanly before you calculate.

What MAT-130 Covers
| Unit | What you do |
|---|---|
| Mathematics of finance | Simple and compound interest, growth over time, loans and savings |
| Counting | Multiplication principle, permutations and combinations |
| Probability | Chances of events, combining events, using counting to find probabilities |
| Descriptive statistics | Mean, median, spread and graphical summaries of data |
| Basic linear regression | Fitting a straight line to paired data and interpreting slope and intercept |
Key Concepts Explained
Compound Interest
Compound interest uses A = P(1 + r/n)^(nt), where P is the starting amount, r the annual rate, n the number of compounding periods per year and t the years.
Example: $1,000 at 5% a year, compounded monthly for 3 years. A = 1000(1 + 0.05/12)^36, which is about $1,161.47. The extra $161.47 is interest earned, and part of it is interest on earlier interest.
Permutations and Combinations
Use permutations when order matters and combinations when it does not. Choosing 3 officers in order from 5 people gives 5 x 4 x 3 = 60. Choosing a 3-person committee gives 60 / 3! = 10.
Regression Line
A fitted line y = a + bx summarizes a trend. The slope b is the predicted change in y for one extra unit of x.
Example (invented data): For points (1,2), (2,4), (3,5), (4,4), (5,5) the least-squares line is y = 2.2 + 0.6x. Each extra unit of x predicts 0.6 more units of y.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Finance problems | Choosing and applying the right interest formula | Write down P, r, n and t before calculating, and state the unit of the answer |
| Counting and probability sets | Telling permutations, combinations and probability rules apart | Ask "does order matter?" and "are events independent?" before choosing a rule |
| Statistics summaries | Computing and interpreting center and spread | Show the list, the calculation and a one-sentence interpretation |
| Regression questions | Reading a line of best fit | Interpret slope and intercept in context, and avoid predicting far outside the data |
A Simple Weekly Plan
MAT-130 moves through four distinct areas, so a steady routine beats cramming. Use something like this and adjust to your calendar:
| Step | What to do |
|---|---|
| Learn | Read the lesson and copy one worked example by hand |
| Practice | Do problems without looking at the solution, then check |
| Review errors | Write the rule you missed next to each wrong answer |
| Mixed review | Once a week, shuffle problems from all units |
A Worked Counting and Probability Example
Find the probability that two fair dice sum to 7. Count outcomes in the sample space: 6 x 6 = 36 equally likely pairs. The favorable pairs are (1,6), (2,5), (3,4), (4,3), (5,2) and (6,1), which is 6 pairs.
Answer: P(sum is 7) = 6/36 = 1/6, about 0.167. Notice the method: define the sample space, count favorable outcomes, divide.
Wording to Tool
Word problems hide the method in a few phrases. Use this table as a quick translator, then confirm with your lesson notes.
| If the problem says | Think |
|---|---|
| Compounded monthly, balance after t years | Compound interest formula |
| Arrangement, order matters | Permutation |
| Select a group, committee, hand | Combination |
| Mean, median, spread | Descriptive statistics |
| Line of best fit, predict | Regression |
Where Students Get Stuck
- Choosing the wrong formula. Identify the type of problem first: finance, counting, probability or statistics.
- Rounding too early. Keep full calculator values until the final step.
- Order and repetition in counting. Decide whether order matters and whether items can repeat.
- Interpreting regression. Say what the slope means in the context of the data, not just its value.
Study Tips for MAT-130
- Make a formula sheet and add the conditions for using each one.
- Check answers for sense: a probability must lie between 0 and 1.
- Estimate first, then calculate, to catch slips.
- Practice word problems more than bare calculations.
