Question

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

Answer 1

$-7 + 9 \neq 9 + 7$

$2 \neq 17$

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.

Answer 2

That's false -7+9=2 and 7+9=18
