Solving Questions

Walk Me Through

Knowre’s Walk Me Through feature offers step-by-step support as you answer questions.
  • Click on the Walk Me Through button on the left-hand side of the screen you need help. You will also be taken to it automatically if you answer a question incorrectly.
  • It costs one coin to access the Walk Me Through, but you will always be able to earn coins back when you retry questions.
  • The Walk Me Through is also interactive so you will need to submit answers at each step or sub-step.
  • There are videos within Walk Me Through that address sub-steps. Be sure to watch these!
  • You can exit the Walk Me Through at anytime by clicking I can solve it now!
  • At the end of each problem, you are given the opportunity to Try Again and re-attempt the question for the opportunity to earn 3 coins.

Answer Input with the Math Palette

Answering open-ended questions are made easy with the math palette, which provides inputs that are not available on a regular computer keyboard.
  • The Math Palette appears as soon as you place your mouse in the answer input box.
  • Select the necessary symbols needed to express the answer appropriately.

Math Palette Closeup

A look at commonly misused or confused math palette buttons.
  • Group 1: Trigonometric Function: Answers that require a trigonometric function must use these buttons. Typing the functions out on a keyboard will result in the answer being marked incorrect.
  • Group 2: Geometric Notation Symbol: You must use these symbols when asked to name figures in Geometry. When naming a segment CD, for example, answers without the bar on top will not be accepted.
  • Button 3: Real Numbers: Used in questions involving domain and range. For the most part, responses involving Real Numbers will be selectable in the form of a checkbox to account for other possible solutions.
  • Button 4: Square: Adds a square to a number or expression.
  • Button 5: Power: Raises a number or expression to the nth power. You must enter in the value for n.
  • Button 6: Empty Set: Used when equations or inequalities have no solution. Responses involving Empty Sets will be selectable in the form of a checkbox to account for other possible solutions.
  • Button 7: Fraction Bar: Creates a fraction. Two numbers, a numerator and a denominator, must be entered.
  • Button 8: Dot Multiplication Symbol: Denotes multiplication. This button and button 9 are interchangeable.
  • Button 9: Times Multiplication Symbol: Denotes multiplication. This button and button 8 are interchangeable.
  • Button 10: Subscript: Creates a subscript. Subscripts are used with sequences and to denote the difference between two variables that have the same letter.
  • Button 11: Absolute Value: Used to notate the absolute value of a number or expression.
  • Button 12: Degree Symbol: Denotes degrees. Frequently used when expressing angle measures.

Answer Input Guidelines

When inputting responses into the answer field, the rule is to put an answer in the same form as the question. The answer should always be in the most simplified form, unless otherwise specified.

Here are some other tips for entering responses:

  • Reduce fractions
  • Combine like terms
  • Evaluate exponents
  • Reduce radicals (after the skill has been learned)
  • Write repeating decimals with an over bar using as few digits as possible.
  • Use double signs only when it is forced by the problem. For solutions of problem with double signs, parentheses must be used between signs. For example, if asked to use the distributive property simplify the expression -2(x+7), the solution can be written as -2x-14 or -2x+(-14), but -2x+-14 cannot be accepted.

Responses should never include the following:

  • Decimals within fractions
  • Fractions within fractions
  • Radicals in the denominator (after the skill has been learned)


Knowre includes many questions that give you a chance to practice your graphing skills.
  • Select the appropriate graph from the graphing palette on the right of the screen, then manipulate it by clicking and dragging the points.
  • You can modify or delete a graph when it is green. If a line or point is red, you won’t be able to modify it. Click the graphing until it turns green, then modify or delete it.
  • Points will “snap” to the grid only in areas where the x axis and y axis intersect. Thus, coordinates that are not whole numbers, such as (-2.5, 3), cannot be graphed.
  • When graphing anything besides a point, do not use more than one graphing element. For example, when graphing a parabola, select the parabola shape from the graphing palette, then manipulate by dragging the points provided. DO NOT select and graph individual points first then overlay a separate parabola over the points. It will be marked wrong!
  • To express limits, drag the bar underneath the graph.
  • For number lines, click and drag the point(s) to reposition in the appropriate spot.
  • Select Change Open/Close to modify the point.
  • Change directions by selecting Change Direction.
