Evaluate powers

Evaluate powers with integer bases and whole-number exponents.

Product and quotient laws of exponents

Simplify expressions like x^5 · x^3 or x^8 ÷ x^2 using exponent laws.

Add and subtract fractions

Add or subtract fractions with unlike denominators; answer in lowest terms.

Order of operations with integers

Evaluate expressions with brackets, powers, and the four operations on integers.

Percent of a number and percent change

Find a percent of an amount, including tax and discount problems.

Unit rates

Compute unit rates and use them to compare or scale real-world quantities.

Collect like terms

Simplify an algebraic expression by collecting like terms.

Distribute and simplify

Expand an expression using the distributive property, then collect like terms.

Exponent laws on monomials

Simplify a product, quotient, or power of a power of monomials using the exponent laws.

Solve one- and two-step equations

Solve one- and two-step linear equations for x.

Solve multi-step equations with brackets

Solve linear equations with the variable on both sides, including equations with brackets.

Translate word problems into equations

Translate a word problem into a linear equation and solve it.

Direct variation

Use direct variation (y = kx) to find a total or a constant of variation in context.

Partial variation word problems

Use partial variation (y = mx + b) to model a fixed fee plus a rate, and solve in either direction.

Identify the equation of a relation from a table

Given a table of values, decide whether a relation is direct or partial variation and identify its equation.

Calculate slope from two points

Calculate the slope of a line given two points on it.

Rewrite in slope-intercept form

Rewrite a linear equation from standard form into slope-intercept form y = mx + b.

Write the equation of a line from slope and a point

Write the equation of a line in the form y = mx + b, given its slope and one point on it.

Rate of change from a table; linear or not

Use first differences in a table of values to find the rate of change, or to recognize a non-linear relation.

Mean, median, and mode

Calculate the mean, median, or mode of a small data set from a real-world context.

Range of a data set

Find the range of a data set as a simple measure of spread.

Correlation from a scatter plot

Classify the correlation shown by a set of paired data as strong positive, strong negative, or no correlation.

Predicting with a line of best fit

Use the equation of a line of best fit to predict a value, and classify the prediction as interpolation or extrapolation.

Angles formed by parallel lines and a transversal

Use angle relationships (corresponding, alternate, co-interior) formed when a transversal crosses parallel lines to find a missing angle.

Interior angles of a polygon

Use the polygon interior-angle-sum formula (n - 2) * 180 to find a regular polygon's interior angle or a missing angle in an irregular polygon.

Area of composite 2D shapes

Find the area of a composite two-dimensional shape by decomposing it into rectangles, triangles, and semicircles.

Surface area of prisms and cylinders

Find the surface area of a rectangular prism, a cylinder, or an open-top prism.

Volume of prisms, cylinders, and composite solids

Find the volume of a rectangular prism, cylinder, triangular prism, or a composite solid made from two prisms.

Simple interest

Use the simple interest formula I = Prt to find interest earned, the total amount, or the principal needed.

Compound interest

Use A = P(1 + r)^n to find the future value or interest earned on a compound-interest investment.

Personal budgets

Build and analyze a simple monthly budget: total expenses, money left over, percent spent on a category, or how much to cut to break even.

Currency exchange

Convert between Canadian dollars and a foreign currency using a given exchange rate.
