$-7 + 9 \\eq 9 + 7$

$2 \\eq 17$

When you add a positive number and a negative number, you get a positive, but the number is smaller. If you add two positive numbers, then of course, you're going to get a positive number as an answer. But overall, this is false.

Is -7 + 9= 9 + 7 true, false or open
