Answer 2

Representing the number 15 using the digits 1, 2, 3, 4, 5, 6, 7, and 8 with one minus sign and three plus signs

To represent the number 15 using the digits 1, 2, 3, 4, 5, 6, 7, and 8, along with one minus sign and three plus signs, we can use the following expression:

8 - 7 + 6 + 5 + 4 + 3 + 2 + 1 = 15

Let's break down the expression:

- We start with the digit 8, which represents the largest value among the given digits. - We subtract the digit 7 from 8, resulting in 1. - We then add the remaining digits in ascending order: 6, 5, 4, 3, 2, and 1. - The sum of these digits is 21. - Finally, we subtract 7 from 21, resulting in 15.

Therefore, the expression 8 - 7 + 6 + 5 + 4 + 3 + 2 + 1 represents the number 15 using the given digits and the specified signs.
