1+12=13+15=28+2=30+29=59.
10
12-3(2+15) = -39
3 + 2(4 + 2) =3 + 2(6) = 3 + 12 = 15
5/15 + 12/15 = 17/15 or 1 and 2/15
15/2 + 27/12 is 9 3/4
15 plus -3 equals 12 12 divided by -6 equals -2
4/5+2/15=12/15+2/15=14/15
2 + 3 * 4 + 1 = 2 + 12 + 1 = 15
7 and 10/15 + 2 and 12/15 = 9 and 22/15 = 10 and 7/15
2/3 + 4/5 = 10/15 + 12/15 = 22/15
