Sample student explanation
One version of the problem is:

Simplify the given expression.

( )
7 + 4 23

A possible student explanation is:

By order of operations, first calculate 2^3 = 8, then multiply by 4 to get 32, then add 7 to get 39..

Note - you don't need to be fancy and type exponents in using an equation tool. For 23 , you can just type in 2^3 (which is how one would type in that exponent in a
spreadsheet program)




Mobius feedback to your problem:



5 + 2 23 ( ) = 5 + 2 (8) Simplify exponent.

= 5 + 16 Multiply.

= 21 Add.

Question2: Score 2/2

Simplify the given expression.


6x + x (10 − 5)


Hint: To enter 7 times y, you can type in either 7y or 7*y. Mobius understands both, but if you want
to be sure that Mobius interprets your answer as 7 times y, then you should type 7*y.



6x + x (10 − 5) =
Your response Correct response
