3 plus 5 is equal to 8.
-1
5 + (-3) + (-5) = -3
3 plus 4 is 7, not 5.
5+n+3 = 8+n
5 + -8 = 3 + 12 -3 is not equal to 15
It is: (2*3)+5 = 11
No, 1 + 2 + 3 + 4 + 5 = 15.
5 plus 3 plus 7 does equal 5 plus 7 plus 3; this is an example of the commutative property of addition. Therefore, the statement is true.
-5 + 3 = -2
3 + 4 = 7, it's not equal to 5, you must have mistaken that for 3 + 2, which gives you 5.
(-5)/(3) = -12/3
