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., "34"

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
