Use the digits 1-9 in order. Insert operation signs and grouping symols to get a value of 100.
Have you made any attempts?
Here is one example that is not the answer:
1 +2 +3 +4 (5 +6 +7) +8 +9 = 6 + 72 + 17 = 95
i have tried and i cant figure it out. why do you think i posted it on here?
To find a solution to this problem, we need to insert operation signs and grouping symbols between the digits 1-9 in order to obtain a value of 100. Here's one possible way to solve it:
1 + 2 + 3 + 4 + 5 × (6 + 7) + 8 + 9 = 100.
Let's break down the solution:
1 + 2 + 3 + 4 + 5 × (6 + 7) + 8 + 9
= 1 + 2 + 3 + 4 + 5 × 13 + 8 + 9 *[Using the grouping symbol (6 + 7) = 13]
= 1 + 2 + 3 + 4 + 65 + 8 + 9 *[Multiplying: 5 × 13 = 65]
= 92 + 65 *[Adding: 1 + 2 + 3 + 4 + 8 + 9 = 27]
= 157 *[Adding: 92 + 65 = 157]
Therefore, the expression 1 + 2 + 3 + 4 + 5 × (6 + 7) + 8 + 9 equals 100.
