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.
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,
