Answer :
Answer:
1 + 2 + 3 + 4 + 5 + 6 + 7 + (8 x 9) = 100
Step-by-step explanation:
Start by adding the numbers from 1 to 7: 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28
Then, multiply 8 by 9 to use the remaining two digits: 8 x 9 = 72
Finally, add the result of step 1 to the result of step 2: 28 + 72 = 100
So, by following these steps, we use each single-digit number from 1 to 9 and apply the operations (+ and ×) to get a total of 100
