Before Calculus: 10 Algebra Skills You Should Know
Ten essential algebra skills with worked examples, common mistakes and self-checks: a practical starting point before university or CEGEP calculus.
Subject area
CEGEP Calculus Tutoring
Prepare for differential and integral calculus in Québec Science programs. Connect algebra, graphs, derivatives and accumulation to the course on your current outline.
Topics covered
Function domains and algebraLimits and continuityDerivatives and their meaningOptimization and ratesDefinite integrals and accumulationIntegration methods and applications
Common difficulties
- Separating an algebra error from a calculus concept
- Distinguishing function value, slope and accumulated area
- Choosing the method when a mixed exercise gives no hint
How tutoring can help
We begin with your actual sequence: differential calculus asks how a quantity changes; integral calculus asks how small contributions accumulate. A graph and units help choose the model before symbolic calculation. Algebra gaps are addressed alongside the new idea, not hidden by a memorized procedure.
Current codes and earlier search terms
These are subject crosswalks for the Science program, not transfer-credit decisions. The prefix matters: 201-SN1 is probability and statistics, while 203-SN1 is mechanics. Local codes and scope vary; your current outline is the reference.

An example that connects the ideas
If position is s(t) = t² metres, its derivative v(t) = 2t m/s describes instantaneous velocity. Integrating v from 1 to 3 seconds gives 8 metres, the displacement s(3) − s(1). Differentiation and integration answer related but different questions.
A question to check understanding
Why is displacement not always total distance? Negative velocity contributes negatively to displacement; total distance accumulates the absolute speed.

Exam preparation

For differential calculus, mix rule selection with complete optimization setups. For integral calculus, practise choosing bounds, checking antiderivatives and interpreting signed area. Use the current outline to decide whether sequences, series or particular integration techniques are assessed.
