# Enter equivalent responses

Möbius recognizes equivalent responses by default.

This behavior is controlled by your instructor in the event that the learning objective of a particular question is for you to demonstrate an understanding of the equivalent expression.

Equivalent responses can be:

- Algebraic equivalence (Example — If the answer to a question is (t+1)
^{2}, a response of (t+1)^{2}or (t^{2}+ 2t + 1) is graded as correct) - Equation equivalence (Example — x
^{2}+ 1 = y is equivalent to y-1 = x^{2}and is graded as correct) - Numeric equivalence (Example — 1/2 is equivalent to 3/6 and is equivalent to 0.5 or 5E-1 and is graded as correct)
- Unit equivalence (Example — 10000 cm
^{2}is equivalent to 1 m^{2}and is graded as correct)

NOTE: Read your question instructions carefully and be sure to enter an appropriate response (Example — if the question asks you to simplify an algebraic expression, you're expected to enter the simplified expression; not the unsimplified expression).
