- Advanced math
- Problem-solving and data analysis
- Geometry and trigonometry
The most common mistakes, unit by unit
Algebra
- Dividing only one term when isolating the variable. Subtracting before dividing in two-step equations →
- Mixing up m and b when an equation isn't written as y = mx + b. Reading slope-intercept form →
- Substituting into the same equation you rearranged in a system. Solving a system by substitution →
Advanced math
- Using the zero-product rule before the equation equals zero. Solving quadratics with the zero-product rule →
- Multiplying exponents that should be added. Exponent rules for multiplying powers →
Problem-solving and data analysis
- Leaving units unconverted in a rate problem. Speed, distance and time →
Geometry and trigonometry
- Adding squares when finding a shorter leg. Using the Pythagorean theorem →
- Labelling opposite and adjacent from the wrong angle. Choosing sine, cosine or tangent (SOH CAH TOA) →
- Using the diameter in place of the radius. Area vs circumference of a circle →
