Mathematics

Advanced algebra through precalculus: complex numbers, sequences and series, polynomial and rational functions, conics, and trigonometry.

About this course

The tenth-grade math course is more advanced than the grade label suggests. It opens with complex numbers, taking your student from the imaginary unit and standard form through complex arithmetic, the complex plane, modulus and argument, polar form, and De Moivre's theorem for powers and roots, then moves into arithmetic and geometric sequences, infinite geometric series, sigma notation, recursive sequences, and proof by mathematical induction. A function unit covers sums, differences, products, and quotients of functions, composition, inverse functions and the horizontal line test, polynomial long division and synthetic division, the remainder theorem, the rational root theorem, Descartes' rule of signs, the fundamental theorem of algebra, multiplicity of roots, and polynomial inequalities solved with sign charts. Rational and radical functions follow, with domain, vertical, horizontal, and oblique asymptotes, holes, extraneous solutions, rational exponents, and partial fraction decomposition.

Two full units are given to the conic sections. Your student analyzes the parabola by focus and directrix, the ellipse by foci and eccentricity, and the hyperbola by foci and asymptotes, identifies conics by completing the square, solves systems involving conics, and then meets parametric equations, polar coordinates, polar curves such as roses and limacons, and conics written in polar form. Trigonometry enters through right triangle ratios, the special 45-45-90 and 30-60-90 triangles, the law of sines, the law of cosines, and the SAS area formula, alongside triangle congruence and similarity, circle geometry, coordinate geometry, geometric proof, and the surface area and volume of composite solids. The algebra units add matrices, determinants, Cramer's rule, augmented matrices and row operations, logarithms and their properties, and exponential growth and decay. The statistics units cover center and spread, the normal distribution and z-scores, scatter plots and least-squares regression, permutations and combinations, geometric probability, inference from a sample, statistical bias, two-way tables, and reading published statistics critically.

The course is 180 lessons across 15 units, one per school day, at about 55 minutes each. The first eight units introduce each strand and the last seven return to the same material with new examples and harder problems. Lessons are written to your student as dense textbook pages, typically a statement of the theorem or formula, two or three fully worked examples, an application, and a practice set, with a KJV verse woven in. Every lesson ends with a ten-question quiz that grades itself. Before starting, your student should have finished a full Algebra I course: factoring, the quadratic formula, exponent rules, function notation, and graphing lines and parabolas are all assumed rather than taught. Freedom Homeschool also offers a separate, dedicated Geometry course at this grade for families who want a full year of proof-based plane geometry; this math course touches geometry but is chiefly an advanced algebra and precalculus course.

What this lesson is for

  • Students will understand and practice Problem Solving - Lesson 7
  • Students will solve problems related to this topic

Train up a child in the way he should go: and when he is old, he will not depart from it.

Proverbs 22:6

Financial mathematics applies algebraic formulas to real-world money management — one of the most immediately practical mathematics topics in the high school curriculum. Simple interest: I = Prt, where P = principal, r = annual interest rate (as decimal), t = time in years. Total amount: A = P + I = P(1 + rt). Example: $2,500 invested at 4.5% simple interest for 3 years earns I = 2500(0.045)(3) = $337.50; total A = $2,837.50.

Compound interest: A = P(1 + r/n)^(nt), where n = number of compounding periods per year. Compare compounding frequencies for $5,000 at 6% for 10 years: annually (n=1): A = 5000(1.06)^10 ≈ $8,954; quarterly (n=4): A = 5000(1.015)^40 ≈ $9,070; monthly (n=12): A = 5000(1.005)^120 ≈ $9,097; daily (n=365): A ≈ $9,110. Continuous compounding (the limit as n→∞): A = Pe^(rt) ≈ $9,111. More frequent compounding yields more interest, but with diminishing returns. APR (Annual Percentage Rate) is the stated rate; APY (Annual Percentage Yield) accounts for compounding and is what you actually earn — for 6% compounded monthly, APY = (1 + 0.06/12)^12 − 1 ≈ 6.168%.

Credit card debt: understand that high-interest debt compounds against you. $3,000 on a credit card at 24% APR compounded monthly: monthly rate = 2%. If you make no payments, after one year: A = 3000(1.02)^12 ≈ $3,804. After five years: $9,850. The Rule of 72: divide 72 by the interest rate to estimate how long it takes an investment to double (at 6%, doubles in about 12 years; at 12%, about 6 years). Activity: solve fifteen financial problems including simple interest, compound interest (all four compounding frequencies), APY calculations, and debt growth scenarios. Calculate how much more compound interest earns over simple interest for the same principal, rate, and term.

Proverbs 21:5 instructs, "The thoughts of the diligent tend only to plenteousness; but of every one that is hasty only to want." Compound interest rewards patience; debt punishes it. The mathematics of finance is one of the most important practical applications of algebra — and one of the most directly connected to the Biblical values of diligence, stewardship, and avoiding the bondage of debt (Proverbs 22:7: "the borrower is servant to the lender"). Every student should leave high school understanding these calculations well enough to make sound financial decisions.

Guided practice

  1. A farmer invests $2,000 in a savings account at 4% annual interest for 3 years. How much interest is earned? (Use I = Prt)

    Show the steps and the answer

    1) Formula: I = Prt. 2) Identify: P = $2000, r = 0.04, t = 3. 3) Substitute: I = 2000 × 0.04 × 3. 4) Calculate: I = $240

    Answer: 240

  2. A young adult deposits $5,000 at 3% annual interest. How much money will they have after 5 years? (Use A = P + I = P(1 + rt))

    Show the steps and the answer

    1) Formula: A = P(1 + rt). 2) Identify: P = $5000, r = 0.03, t = 5. 3) Substitute: A = 5000(1 + 0.03 × 5). 4) Calculate: A = 5000(1.15) = $5750

    Answer: 5750

  3. How long will it take $8,000 to earn $960 in interest at 6% annual interest? (Use I = Prt, solve for t)

    Show the steps and the answer

    1) Formula: 960 = 8000 × 0.06 × t. 2) Simplify: 960 = 480t. 3) Solve: t = 960/480. 4) Calculate: t = 2 years

    Answer: 2

Note for the parent

Today's lesson covers Problem Solving - Lesson 7. Estimated time: 55 minutes. Encourage independent work but be available for questions.

The first three of this lesson's 10 questions

Simple interest is calculated as I = Prt, where P = principal, r = annual rate, t = time in years. The formula for total amount A =

  1. A = Prt
  2. A = P + r + t
  3. A = P(1 + rt)
  4. A = P^(rt)
Show the answer

Answer: A = P(1 + rt)

$2500 at 4.5% simple interest for 3 years earns I = 2500 * 0.045 * 3 =

  1. $112.50
  2. $1125
  3. $3.38
  4. $337.50
Show the answer

Answer: $337.50

Compound interest formula: A = P(1 + r/n)^(nt). Here 'n' is the number of:

  1. Years
  2. Compounding periods per year
  3. Dollars in principal
  4. Interest payments made
Show the answer

Answer: Compounding periods per year

Another 7 questions follow in the lesson itself, each one graded the moment it is answered.
