Answer key for problems 501 thru 550 is completely different than the original questions.
Good book over all, but HUGE miss on on the answer key being wrong for 50 problems.

One problem in the book
Great book. My grandson needed more practice for homeschool , so we got this for him. One problem, page 100-150 the problems do not match the answer problems. Answer problems are totally different problems.

Answer key is wrong. Worst book.
As per other comments, the solution is wrong from 501. The publisher should make corrections.
