4 + 6 + 12 + 175 = 197
14 ! If n=12, then 12-4 is 8, plus 6 is 14
4+4=12 12+6=18 18+6=24 24+10=34 34+10=44
12 *6+4=76
It is the commutative property of addition.
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
1/12 + 4/6 = 1/12 + 8/12 = 9/12 = 3/4.3 over 4 is 1 over 12 plus 4 over 6.
2/12 + 2/12 + 4/12 + 9/12 + 6/12 = 23/12 or 1 and 11/12
2/4 = 6/12 4/12 + 6/12 = 10/12 10/12 simplifies to 5/6
x=12 because 12 over 6 is 2,and 2 plus 4 is 6.
16/12 or 4/33/4 * 3/3 = 9/121/2 * 6/6 = 6/12................1/12===========...............16/12 or 4/3
12 - 10 + 4 = 6
-5 + (-4) - 12 - 20 - (-10) + 6 = -25
