SUMMARY

The discussion revolves around solving a mathematical expression using the numbers 1 through 9 in consecutive order to equal 100, without the use of parentheses. Participants provided multiple solutions, including the expressions "1 + 23 * 4 + 5 - 6 + 7 - 8 + 9 = 100" and "1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 * 9 = 100". The constraints specified that standard arithmetic operations (addition, subtraction, multiplication, and division) could be used, but the order of numbers could not be altered. The challenge emphasizes creative problem-solving within defined mathematical rules.

PREREQUISITES
  • Understanding of basic arithmetic operations (addition, subtraction, multiplication, division)
  • Familiarity with the concept of consecutive integers
  • Knowledge of mathematical expressions and their evaluation
  • Ability to manipulate numbers to achieve a target value
NEXT STEPS
  • Explore advanced techniques in combinatorial mathematics
  • Research mathematical puzzles and their solutions
  • Learn about number theory and its applications in problem-solving
  • Practice creating expressions with constraints similar to those in this discussion
USEFUL FOR

Students, educators, and math enthusiasts looking to enhance their problem-solving skills and explore creative approaches to mathematical challenges.

There's a problem on my math homework that I really don't get. I couldn't find it anywhere else on the internet, so I came here. I have to use the numbers
1, 2 ,3, 4, 5, 6, 7, 8, and 9 and I can multiply, divide, add, and subtract, but I can't use parenthesis
to make an expression that will equal 100. I played around for a while and didn't get anything. Plus, I can't use the expression
123-4-5-6-7+8-9=100, because that's the example they gave in the book.
So, could someone help me out here? Thanks. :smile:

23*5 - 9 - 8 - 7 - 1 + 6 + 4
That's also one.
 
Thanks! :smile:
 
Whoops! I forgot to say that the numbers had to be in consecutive order. Crap. Well, thanks anyway.
 
1+23*4+5-6+7-8+9=100:smile:
1+2+3+4+5+6+7+8*9=100:smile:
