I like examples because examples have me understand better such as
25 + 16 = 41
41 - 32 =9
A = 25 - 9 = 16
B = 16 - 9 = 7
U = 13 - 7 = 6
or examples:
(a) 8 Juniors
(b) 8 seniors
(c) 8 seniors + 12 = 20
(d) guards or centers
8 + 3 + 4 + 4 + 1 = 16
(e) seniors who are not center or college students who are not guards
4 + 8 + 9 + 1 = 22
(f) junior high seniors who are are not centers
8 + 5 = 13
