Question

create a mathematical problem using 4 numbers with addition and subtraction that results in an answer of 7.

Explanation:

Step1: Choose 4 numbers

Let's pick 5, 3, 2, and 1.

Step2: Combine with + and -

Arrange them: \(5 + 3 - 2 + 1\).

Step3: Calculate

First, \(5 + 3 = 8\), then \(8 - 2 = 6\), finally \(6 + 1 = 7\).

Answer:

\(5 + 3 - 2 + 1 = 7\) (Other valid combinations like \(10 - 5 + 3 - 1 = 7\) are also acceptable)
