Enter algebraic expressions with a keyboard

Updated 05 Mar 2024

You can enter an algebraic expression with correct notation using simple and, in many cases, quite natural keyboard characters.

You can also use a palette (if provided) for answering expression questions.

 

• To divide, use a slash /. To multiply, use an asterisk *.
• To group, use parentheses ( ): 3/(x*4)
• To enter powers, use a caret ^, x^2
• To enter square roots, use the sqrt function: sqrt(2)
• Use the functions log (log base 10), ln (natural log), arccos, arcsin, arctan, sin, cos, and tan, e.g., arccos(1)
• Use the constants pi and e
• For the sin, cos, and tan functions, enter arguments in radians, e.g., sin(pi/3)
