Once I saw the videos about math, I understood exactly what he was doing wrong. He had twenty-eight donuts and he thought that seven times thirteen is twenty-eight. Therefore, when he showed the other people on the chalk board, He divided seven into twenty-eight and he got one for the first step. Then, he “re-used” the two from before. That gave him twenty-one. After that he stated that seven goes into twenty-one, three times. That’s how he got thirteen. In math you just can’t “re-use” numbers. If it can’t go in to one number, you move on and continue the equation. He messed up, so the officers will get less donuts than what they were expecting.
