[AI-generated answer — Explain Bot]

To solve the expression 31 - √31 + √31, you need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

In this case, there are no parentheses, exponents, or multiplication/division operations, so we can directly focus on performing addition and subtraction from left to right.

Starting from the left, we have:

31 - √31 + √31

To simplify this, we can combine the two square root terms:

31 + (√31 - √31)

The square root terms cancel each other out, leaving us with:

31 + 0

Therefore, the answer is 31.
