# How do I enter math symbols in an exercise?

Hello, brilliant learners! We've got some tips to make your math journey smoother when completing math exercises. Let's dive into using our math keypad and LaTeX commands.

**The Math Keypad**

When using the math keypad, note that it changes based on the exercise, showing only the symbols you need.

**On desktop computers:**

Spot a button near the exercise input? Click it to reveal or hide the math keypad.

**On Mobile:**

For math inputs, a special keypad pops up automatically.

Keep in mind: Using the math palatte is a slightly different experience when in a test or quiz vs when using it with Khanmigo.

**LaTeX: Your Math Typing Tool**

Some exercises have a special keypad for math symbols. But sometimes, you'll need to type them. That's where LaTeX comes in handy. Here are some common LaTeX commands:

**Multiplication:** Use an asterisk (*). E.g., "3*4"

**Division: **Use a slash (/). E.g., "3/4". For operations in the numerator or denominator, use parentheses. E.g., "12/(5n)" or "(n+3)/6"

**Square root:** Type "sqrt(x)". E.g., "sqrt(3)"

**Pi:** Type "pi"

**Theta (θ):** Type "theta"

**Powers or exponents:** Use a caret (^). E.g., "4^5"

**Fractional exponents:** Use a caret (^) and type the fraction in parentheses. E.g., "x^(1/3)"

**Greater than or equal to:** Type ">="

**Less than or equal to:** Type "<="

**Logarithms: **For base 10, enter "log(x)". For natural logarithms, enter "ln(x)"

**Logarithms with other bases:** Enter as "log_b(n)", where b is the base and n is the number
