Numeric entries can be read by the system in the following styles:

Optional thousands separators can be used, so that 1,234 and 1234 will both be accepted.

Dollar signs will not be accepted in your answers.

You can use scientific notation in your answer, for example 2.37E3 in place of 0.00237.

You can enter arithmetic expressions for your answer. For example if you enter 2.35+0.11 the system will grade it as though you had entered 2.46.

Negative numbers are denoted with a minus sign. For example, 27.5.
