Requirements
● Comfort with basic arithmetic (addition, subtraction, multiplication, division)
● A calculator or a spreadsheet (Excel, Google Sheets, Numbers, or LibreOffice Calc)
● A notebook or digital notes app to work through the assignments
● No prior finance, accounting, or statistics background is required - every concept is built from the ground up
● Basic English comprehension (English audio with English subtitles provided)
Description
This course contains the use of artificial intelligence.
Every professional decision involves numbers, and yet most professionals were never taught the practical math that sits behind them. This course closes that gap. In around three hours of focused video, you gain the complete toolkit of business mathematics the same toolkit used daily by financial analysts, operations managers, business owners, and consultants through plain-English explanations, worked numerical examples, and animated visual derivations.
The course is organized into seven sections and thirty lectures, each lecture averaging five to seven minutes. Every concept is grounded in a real workplace scenario so you see not only how a formula works but also why it matters, when to apply it, and what business decision it supports.
Why this course exists
You already work with numbers every day. You read reports, interpret dashboards, approve budgets, set prices, sign purchase orders, review invoices, and evaluate proposals. You know the numbers matter, but you may not always feel fluent with the math behind them. You may defer to the finance team when a calculation comes up in a meeting. You may second-guess your own estimates. You may miss opportunities to challenge a proposal or catch a costly error.
This course fixes that. You do not need a finance degree, an accounting background, or a quantitative major. You need practical, confident fluency with the formulas that drive real-world business decisions. That is exactly what you build here.
What you learn in this course
By the end of the course, you will be able to
• Apply order of operations, percentages, ratios, and proportions accurately and quickly in any business context.
• Convert fluidly between fractions, decimals, and percentages, and use rounding and estimation to check your work.
• Calculate markup, margin, and discount pricing for any product or service.
• Use simple and compound interest formulas to evaluate loans, savings, and investments.
• Apply the time value of money, present value, future value, net present value, and internal rate of return to any capital decision.
• Build and interpret loan amortization schedules for mortgages, car loans, and business financing.
• Compute return on investment, break-even points, and margins of safety for any project.
• Describe data using the mean, median, mode, range, variance, and standard deviation.
• Build and read bar charts, line charts, pie charts, and histograms without creating misleading visualizations.
• Use probability rules, expected value, and sampling with confidence intervals to quantify business uncertainty.
• Classify costs as fixed, variable, mixed, or step, and separate them using the high-low method.
• Run contribution margin and cost-volume-profit analysis to evaluate any pricing or volume decision.
• Apply the four major depreciation methods, plus MACRS for United States tax depreciation.
• Compare FIFO, LIFO, weighted average, and specific identification inventory valuation methods.
• Build operating budgets, capital budgets, and cash flow forecasts, and run variance analysis against them.
• Use the economic order quantity formula and reorder-point logic to optimize inventory ordering.
• Calculate complete payroll from gross pay through federal income tax, FICA, state tax, pre-tax deductions, post-tax deductions, and net pay, and understand the total cost of employment for the employer.
• Integrate all of these tools into a single real-world capital investment decision through a coffee-shop expansion case study.
What makes this course different
• Every lecture uses animated visual derivations. Formulas appear on screen built up piece by piece, tables grow row by row, and bar charts animate from zero. You see the math happen.
• Every topic is taught with real business scenarios. You never learn a formula in isolation. You learn it inside the pricing decision, the inventory policy, the loan comparison, or the capital budget that gave rise to it.
• Every section includes quizzes, assignments, and role-plays. You are not a passive viewer. You practice with multiple-choice quizzes that model real workplace questions, hands-on assignments you complete in a spreadsheet, and role-play activities where you step into the shoes of a purchasing clerk, a pricing analyst, a loan officer, a market researcher, a financial analyst, or an operations manager.
• The course ends with a complete capstone case study. You apply every tool in the course to one integrated decision - should Sarah open a second coffee shop location for a one-hundred-fifty-thousand-dollar capital investment? You project revenue through triangulation, classify and compute costs, run break-even and margin of safety, evaluate the capital budget, compute net present value at a ten-percent discount rate, run sensitivity analysis, and deliver a defensible recommendation.
The complete curriculum
Section 1 Foundations of Business Math (4 lectures).Order of operations with PEMDAS, fractions and decimals and their conversions, percentages in plain and applied form, and rounding and estimation as speed tools. This section is the vocabulary every later section builds on.
Section 2 Percentages, Ratios, and Proportions (5 lectures). Percentage change over time, the distinction between markup and margin, discount calculations, business ratios and proportions, and sales tax, tips, and commission calculations that appear in daily transactions.
Section 3 Financial Mathematics (5 lectures).Simple and compound interest, the time value of money, loan amortization schedules for mortgages and car loans, return on investment, and break-even analysis. This section is the heart of any financial decision you will ever make at work or at home.
Section 4 Business Statistics Essentials (5 lectures).Measures of central tendency, measures of spread, data visualization best practices, probability for business decisions, and sampling with confidence intervals for market research and quality control.
Section 5 Profit, Loss, and Cost Analysis (4 lectures).Revenue, cost, and profit fundamentals, detailed cost behavior classification, contribution margin and cost-volume-profit analysis, and depreciation of long-lived assets across five different methods.
Section 6 Operations and Decision Math (4 lectures).Operating budgets, capital budgets, and cash flow forecasts with variance analysis; inventory valuation under FIFO, LIFO, weighted average, and specific identification; economic order quantity and reorder-point inventory management; and complete payroll calculation with employer-side taxes and benefits.
Section 7 Comprehensive Wrap-up (3 lectures).A systematic review that connects every topic into one integrated framework, a capstone real-world case study that applies every tool to a single decision, and a final lecture on continued learning, spreadsheet functions, recommended books, and lifelong practice habits.
How you practice what you learn
Each of the six content sections includes a multiple-choice quiz with detailed answer explanations, a practical assignment you complete in a spreadsheet or by hand, and a role-play activity in which you take on a specific workplace role. Quiz questions are modelled on the kinds of quantitative questions that arise in team meetings, budget reviews, and project proposals. Assignments require you to build actual spreadsheet models you can reuse forever. Role-plays push you to integrate multiple concepts at once, just as real work does.
The capstone case study in Section 7 gives you the complete experience of running a quantitative analysis end to end, from initial data to final recommendation.
