In this post, you will be given four different number puzzles. They range from medium difficulty all the way to impossible. Admittedly, the last puzzle shown does not have a solution. Or rather, I do not know the solution to the puzzle. This is despite me having seen the solution in the past & I will provide you with what I remember in the hints section. IF you solve it, please provide the answer in the comments section.
Back to the challenge. You will have to find the missing operands to make each of the equations true.
Question 1 (easy):
Question 2 (medium difficulty):
Question 3 (difficult):
Question 4 (unsolvable):
For question 3, Factorials (see wikipedia) will help!
And herewith the answers. There may be multiple answers to the questions. I present an answer, which may not always be the most elegant solution.
For those who do not have a calculator close by ;),
1. 9 times 8 = 72
2. 9 – 6 = 3
3. 72 divided by 3 = 24
This is one solution. I am sure there are more elegant ones out there. Feel free to post these in the comments section.
