What you'll build
What you will be able to do
Each lab ends with a concrete result that you build yourself and the checker confirms, cell by cell.
- Evaluate four expressions for x from −3 to 4 and learn where Excel's order of operations differs from the textbook.
- From two car-share bills you find the price per km and the fixed fee, build a table of values and graph the line.
- Solve a one-step budget equation, then a system of two equations for adult and student tickets with the determinant (Cramer's rule).
- Find when a thrown ball is highest and when it lands, then use the discriminant to count the real roots of four quadratics.
- Model how caffeine leaves the body with a half-life, graph the decay curve, find a bacteria culture's growth factor from two counts and predict a later count.
- Use LN to solve exponential equations for the time, and LOG10 to convert sound intensities into decibels and back.
- Test ten production plans of a school fundraiser against three inequalities and find the best plan that respects all of them.
- Find the root of x³ − 2x − 5 between 2 and 3 by halving the interval again and again until it is narrower than 0.001.
About this course
Algebra is easier to grasp when you can change a number and instantly watch the result move. That is the approach of this course. You evaluate expressions while respecting order of operations, graph linear functions from slope and intercept, and solve single equations and two-by-two systems. Quadratic labs find the vertex, the roots and the discriminant. You model exponential growth and decay with growth factors and half-lives, then use natural logarithms to solve for the time it takes to reach a value. Inequalities are tested as feasible regions, and the final lab finds a root numerically with the bisection method. Ideal for secondary school and college students, adult learners refreshing their maths and teachers looking for practice material.

Before you buy
Questions about this course
Is this a subscription?
No. You pay $9.99 once for this course. There is no subscription and nothing renews automatically. Prices are in US dollars; taxes may be added where required.
What exactly do I get?
All lessons and labs of this course, the final exam and the certificate, including later updates to the course, for as long as Tutorvo offers it. Access is personal and tied to your account.
Can I get a refund?
Yes. If you are not satisfied, email hello@tutorvo.com within 14 days of buying and we refund the course in full via Stripe. The guarantee does not apply once a certificate for the course has been issued to you, or where there are signs of abuse.
When can I start?
Right after payment. Access starts immediately at your request; for consumers in the EU/EEA the statutory right of withdrawal therefore ends once access has begun, while our 14-day money-back guarantee applies regardless.
Do I need Excel or other software?
No. The labs run in a spreadsheet inside your browser on a laptop, tablet or phone. Function names and syntax follow Excel.
Is the certificate an official qualification?
No. It confirms that you completed all lessons of the course and passed its final exam. It is not an official, state-recognised or professional qualification. The name is taken from your profile when the certificate is issued.
