**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
