My child is working through basic operations, and gave this problem: 23 + 17 * 2 / 8 + 11 = 13 The teacher wants the parenthesis to be put in the right places to come up with 13. My father is a former math teacher, and he could solve, I asked a couple of financial engineer I work with and they could get it. Now I'm asking you, please help. Other wise I will have to kill the teacher.
Regards, The answer expected is probably When I first looked at it I thought there must be a misprint. If 13 is a misprint and should be 3 then: If with *2 being a misprint then: The point of these exercises is to show how important parentheses are. The students who do not realize this have lots of problem in high school algebra. Cheers,Claude
