Answer 2

It seems like you've written a sequence of mathematical expressions separated by commas. Let's break them down one by one:

1. 0: This is a simple expression that evaluates to zero.
2. 7 * 1: This is the multiplication of 7 and 1, which equals 7.
3. 3 + 5: This is the addition of 3 and 5, which equals 8.
4. 1 ÷ 0: Division by zero is undefined in mathematics, so this expression is not valid.
5. 17 - 40: This is the subtraction of 40 from 17, which equals -23.

So, in summary:

• 0 = 0
• 7 * 1 = 7
• 3 + 5 = 8
• 1 ÷ 0 is undefined
• 17 - 40 = -23
