ALEKS math answers, topic by topic
Canvas Quiz Solver shows ALEKS math answers on the page, under each typed problem: expressions, exponents, fractions, intervals and problems with tables. You type the answer into the ALEKS answer editor. Below the setup, the topics students search most each get a worked method with made-up numbers.
Canvas Quiz Solver shows ALEKS math answers under each typed problem in Learning mode, Knowledge Checks and assignments (beta). It reads expressions, exponents, fractions and tables, and for graph problems it lists the points or the shape to draw. You type the answer yourself. It stays off on LockDown Browser and placement tests.

How it works on ALEKS math
Three steps, and you stay the one who answers.
- Add Canvas Quiz Solver to Chrome. It is free to add, and you get free answers to try it on a real problem.
- Open your ALEKS math topic. A Learning mode problem, a Knowledge Check or an assignment.
- Read the answer card under the problem. Type the answer into the ALEKS answer editor, then press Check or Submit yourself.
The honest limits: the extension does not type into ALEKS. It is off on LockDown Browser and Respondus pages and on placement tests. Answers come from AI and can be wrong, so read each one.
What the extension reads in ALEKS math
ALEKS math is mostly typed answers: a statement with math in it, sometimes a table, and an answer box.
Canvas Quiz Solver reads the math in the statement (expressions, exponents, fractions and units) and the rows of a table, and shows the answer under the problem. On a graph problem it lists the points or the shape to draw, and you draw it with the ALEKS tool. You type every answer into the ALEKS answer editor.
The methods below use made-up numbers. They are not ALEKS problems, and your numbers will be different, so follow the steps.
Union and intersection of intervals
Draw both intervals on one number line: the intersection is where they overlap, the union is everything either one covers.
Write each interval with its brackets. A square bracket [ ] includes the endpoint, a round one ( ) leaves it out, and ∞ always gets a round bracket.
For the intersection, take the larger left endpoint and the smaller right endpoint, each with its own bracket. For the union, if the intervals overlap or touch, take the smaller left endpoint and the larger right endpoint. If they do not overlap, the intersection is the empty set ∅ and the union is written as two pieces joined by ∪.
A = (−3, 5] and B = [2, 8). Find A ∩ B and A ∪ B.
The 2 is included because B includes it and A covers it; the 5 is included because A includes it and B covers it.
Find (−∞, 1) ∩ [4, ∞) and (−∞, 1) ∪ [4, ∞).
The union cannot be merged into one interval because 1 to 4 is missing.
Common input mistake: copying the bracket from the wrong interval. Each endpoint keeps the bracket of the interval it came from.
Inequalities in interval notation
Solve the inequality first, then turn the solution into brackets: "≤" and "≥" give [ ], "<" and ">" give ( ).
Solve like an equation, with one extra rule: when you multiply or divide both sides by a negative number, flip the inequality sign.
A compound inequality with "and" is one interval. A compound inequality with "or" is usually two intervals joined by ∪.
Write the solution in interval notation: (a) −2 ≤ x < 7; (b) 3x − 4 > 11; (c) x < −1 or x ≥ 3.
Infinity never takes a square bracket.
Common input mistake: forgetting to flip the sign after dividing by a negative, for example −2x > 6 gives x < −3, not x > −3.
Evaluating and simplifying expressions
Substitute with parentheses, follow the order of operations, and use the exponent rules one at a time.
When you plug in a negative number, put it in parentheses first. (−3)2 is 9, but −32 is −9.
For exponents: multiply powers of the same base by adding the exponents, raise a power to a power by multiplying them, and raise each factor in a product to the power.
Evaluate x2 − 4x + 1 when x = −3.
The minus times minus in −4(−3) is where most errors happen.
Simplify (2a3)2 · a.
The 2 is squared too: (2a3)2 is 4a6, not 2a6.
Common input mistake: typing the exponent as a plain number next to the base, which turns a7 into a7. Enter it as an exponent.
Functions and the vertical line test
A relation is a function when every input x has exactly one output y; on a graph, no vertical line crosses it twice.
For a list of ordered pairs or a table, look for a repeated x value with two different y values. One repeat with different outputs means it is not a function. A repeated y value is fine.
For a graph, imagine sliding a vertical line from left to right. If it ever touches the graph at two points, it is not a function. A parabola that opens up (y = x2) passes; a parabola that opens sideways (x = y2) and a circle fail.
Which relation is a function? R = {(1, 2), (3, 4), (1, 5)} or S = {(−2, 4), (2, 4), (0, 0)}.
In S, two inputs share the output 4, and that is allowed.
Common input mistake: reading the test sideways: a horizontal line crossing twice does not stop a graph from being a function.
Probability
Count the outcomes you want, divide by all equally likely outcomes, and use the rules for "or", "and" and "not".
Addition rule: P(A or B) = P(A) + P(B) − P(A and B). Multiplication rule for "and": multiply, and if the first pick is not replaced, the second fraction changes. Complement: P(at least one) = 1 − P(none) is often the fastest route.
Leave answers as fractions in lowest terms unless the problem asks for a decimal or a percent.
(a) Two fair dice are rolled. Find P(sum is 7). (b) A bag has 4 red and 6 blue marbles. Two are drawn without replacement. Find P(both red).
In (b), the second fraction is 3/9 because one red marble is gone.
(a) P(A) = 0.45, P(B) = 0.30, P(A and B) = 0.12. Find P(A or B). (b) A fair coin is flipped 3 times. Find P(at least one head).
Subtract P(A and B) so the overlap is not counted twice.
Common input mistake: giving 12/90 instead of 2/15. Reduce fractions before you submit.
Slope and the equation of a line
Find the slope from two points, then put one point and the slope into point-slope form.
Slope is rise over run: m = (y2 − y1) / (x2 − x1). Subtract in the same order on top and bottom. A horizontal line has slope 0, and a vertical line has no slope (undefined).
Point-slope form is y − y1 = m(x − x1). Solve it for y when the problem asks for slope-intercept form, y = mx + b.
Find the equation of the line through (−1, 4) and (3, 12) in slope-intercept form.
Check with the other point: 2(3) + 6 = 12.
Common input mistake: writing x − 1 instead of x + 1 for the point (−1, 4). Subtracting a negative gives a plus.
Proofs
Each line of a proof is a statement plus the reason it is true: given, a definition, a property or a theorem.
Start from the given and write down what you must prove. Then work toward it one small step at a time, so that every step uses a reason you can name: definition of congruence, reflexive property, segment addition, substitution, and so on. Algebra proofs work the same way: each line is an equation, and the reason is the property you used to get it.
If your proof problem uses a special input tool and the card does not read it, use this method and check each reason yourself. Try the free answers on your own proof first.
Points A, B, C and D lie on a line in that order. Given AB = CD, prove AC = BD.
Step 2 looks obvious, but a proof needs it written down.
Prove: if 2(x + 3) = 14, then x = 4.
Name the property, not the arithmetic: "subtraction property of equality", not "minus 6".
Common input mistake: giving a reason for the wrong step, for example "substitution" where the step only adds the same thing to both sides.
Why posted ALEKS math answer keys miss
A solution PDF or a forum answer solves a problem that is not yours.
Search results for ALEKS math answers are mostly old exam keys, practice sites and forum threads. Even when the topic matches, a single changed number changes the answer: if your interval is (−3, 6] instead of (−3, 5], the posted intersection is wrong for you.
The methods above work with any numbers, and the extension reads your problem with your numbers.
Where it stays off
It is off on LockDown Browser and Respondus pages and on ALEKS placement tests.
ALEKS lets schools require Respondus LockDown Browser, and optionally Respondus Monitor, on Quizzes, Tests and Scheduled Knowledge Checks, and on placement assessments in ALEKS PPL (ALEKS and Respondus FAQs). The extension does not run there, and it gets around nothing. More in does ALEKS record you.
