The baker had two numbers 7 and 28. When he was dividing them, he did 7 into 2 which didn't work then 7 into 8 which was one them subtracted them which is one then dropped down the 2 and got 21 and 7 went into 21 3 times which equaled 13. Instead he should have put 7 into 2 which wouldn't have worked then 7 into 28 which is 4. When he was multiplying the 13 and 7 he should of done this.( he needs to add the 0) 13

* 7

---

21

+70 <- +0

---

91

When he was adding them, he needed to add all 7 threes which is 21. Put the 1 as the ones place in the total and add the two to the the other 7 ones and add the 7 ones up which is seven, then he should have added 2 to get 9. As a total he should have gotten 91.
