Answer key
What is in this set
The numbers in this set run from 2 to 15.
Every problem in it will have brackets to clear first.
A careful solution takes 3 written steps on average.
The mistake this set invites most often, in 100% of the problems: the bracket was multiplied out one term at a time and the second term never got the multiplier.
Answers are a whole number.
Drawing 240 problems from this page produced 238 different ones, 99% — so a sheet of 20 is a new sheet almost every time.
We would put this in front of a grade 6 class. That is our judgement, not a standard, and it is printed here so you can disagree with it. Everything else we put in that year.
