DeltaMath skill guides
Each guide covers one DeltaMath skill: what the problem asks, the steps in order, a fully worked example, the mistakes that get marked wrong most often, and how to type the answer.
Pre-Algebra
1 guideAlgebra 1
6 guides- Algebra 1Finding the Slope GraphicallyDeltaMath shows a line drawn on a coordinate grid and asks for its slope. Sometimes two points are marked; often you have to find your own lattice points.DeltaMath skill: Finding Slope Graphically
- Algebra 1Systems of Linear Inequalities GraphicallyYou are given two (sometimes three) linear inequalities and must either graph the solution region using DeltaMath's drawing tool or decide whether a given point is a solution.DeltaMath skill: Linear Inequality Systems Graphically
- Algebra 1Slope From Two PointsDeltaMath gives two ordered pairs, often with negative coordinates, and asks for the slope of the line through them.DeltaMath skill: Slope From Two Points
- Algebra 1Graphing Lines in Slope-Intercept FormDeltaMath gives an equation such as y = −3/2 x + 4 and asks you to draw the line by placing two points on the grid.DeltaMath skill: Graphing Lines (Slope-Intercept Form)
- Algebra 1Solving Systems of Equations by SubstitutionTwo linear equations, at least one already solved for a variable (or easy to solve). You find the single (x, y) pair that satisfies both.DeltaMath skill: Systems of Equations (Substitution)
- Algebra 1Factoring Trinomials (a = 1)A trinomial with leading coefficient 1, such as x² − 5x − 24. You enter the factored form.DeltaMath skill: Factoring Trinomials (a = 1)
Algebra 2
3 guides- Algebra 2Solving Quadratics With the Quadratic FormulaA quadratic equation, sometimes not yet set equal to zero, that must be solved exactly. Answers may be rational, irrational with a radical, or complex depending on the course level.DeltaMath skill: Quadratic Formula
- Algebra 2Simplifying RadicalsA square root (sometimes a cube root) of a whole number or a monomial with variables, to be written in simplest radical form.DeltaMath skill: Simplifying Radicals
- Algebra 2Evaluating LogarithmsA logarithm with a numeric base and argument, such as log₃ 81, log₅ (1/25), or ln e⁴, to be evaluated exactly.DeltaMath skill: Evaluating Logarithms
