Sample student explanation
One version of the problem is:
Simplify the given expression.
3
7 + 4 (2 )
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)

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.

( t − 8)2
6
A possible student explanation is:
Multiply 9/6 t and 8 each by 2 to get 18/6 t - 16. Because 18/6 = 3, this simplifies to 3t – 16.

Question4: Score 2.5/5
There is a mound of g pounds of gravel in a quarry. Throughout the day, 300 pounds of gravel is
added to the mound. Two orders of 600 pounds are sold and the gravel is removed from the mound.
At the end of the day, the mound has 1,200 pounds of gravel.
Solve for g .
