Adding math expressions to questions

The Math input feature lets you embed mathematical formulas and equations into your test questions using a built-in virtual keyboard or by typing TeX expressions directly.
April, 2025

Ideal for math-heavy assessments involving algebra, calculus, trigonometry, or scientific notation, Math input will cover all your math question needs.

Methods of entry

You can choose between two input methods:

1. Using the virtual math keyboard

The virtual keyboard provides categorized buttons that insert TeX expressions automatically. Access the virtual keyboard by clicking the keyboard icon located at the right side of the "TeX Entry with virtual keyboard" input field.

Note that each layout will have its alternative version accessible via the "Shift" key, represented by an upper arrow symbol.

Buttons are grouped into tabs such as below.

Basic numbers: numbers 0 to 9, arithmetic operators (+, −, ×, ÷), parentheses, equality/inequality symbols, superscripts, fractions and others.

Symbols\sin, \cos, \tan, \log, \ln, \exp and Greek letters (α, β, θ, π), infinity (∞), lim, constants (e.g., e), integral \int, derivative \frac{d}, limits \lim, summation and others.

Example use cases:

Powers and exponents: to enter 2^5, click the blue square and blank square button, then type 2 as the base and 5 as the exponent. Alternatively, click shift at the basic numpad layout and choose the blue square with the correct power value.

Square roots and nth roots: click √ from the right section of the panel. To enter 16\sqrt{16}16​, type inside the placeholder.

Fractions: click the abc tab and then click the shift key presented on the left side of the virtual keyboard. Number 5 key will be transformed into a blank fraction symbol, allowing you to enter a fraction value.

Trig functions: use the respective buttons such as sin, cos and others and enter the value. You can access additional format by pressing the shift key to enter more complex trigonometry values.

Integrals: click the ∫ key and fill in the bounds as needed.

Limits: click the lim key, then add the limit expression and target.

Summation: Select ∑ to insert a summation value.

Each button fills in the correct TeX structure either directly or with placeholders. You can click into the placeholders and edit the values with your keyboard.

2. Typing TeX manually

If you’re comfortable with LaTeX/TeX syntax, just click into the input field and start typing.

Examples:

x^2 + y^2 = z^2 → x2+y2=z2x^2 + y^2 = z^2x2+y2=z2
