No it does not.
Yes. 5 + 3 + 7 = 15 and 5 + 7 + 3 = 15
5+7 = 12 12 times 6 = 72 add the 3 to get 75.
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.
7 + 5 = 12 12 x 6 = 72 72 + 3 = 75 3 + [6 x (5 + 7)] = 75 3 + [6 x 12] = 3 + 72 = 75
7 plus 75 is 82.
This equation is not possible. Two plus three plus four plus five does not equal 287. The system has no solution.
-75
75 = 5 * 5 * 3 105 = 5 * 7 * 3
true. 5+3=8 8+7=15 5+7=12 12+3=15
3+6+5+7+(9-7)=23
Addition
5 + 2 + 3 + 7 + (21/7) = 20
