i	X	Y
A	2	4
B	2	1
C	5	3
D	6	7
E	1	2
F	3	4
G	1	2
H	1	7

a. ΣX        b. Σ(X - Y)         c. ΣX²        d. Σ(X)²

e. (ΣX)²        f. Σ(Y - X)³        g. ΣXY        h. ΣX - ΣY

F	8	5
G	8	4
H	2	3

a. ΣX            b. ΣY            c. ΣXY            d. ΣX²

e. (ΣX)²            f. (ΣXY)²        g. (ΣX)(ΣY)        h. Σ(X - 3)

i. Σ(X - 2)(Y - 3)        j. Σ(Y - 3)²
