The areas shaded with the / and \ characters in this example are ranges.
The first range
(I)
is referenced by RIC I : R7C5. The second range (\) is
referenced by R4C3: RIIC7.
Both shaded areas together comprise a union. The union is referenced by
RICI: R7C5, R4C3: RIIC7.
The intersection of the two shaded areas is shown in this example by x
characters. The intersection is referenced by
name1 name2. Name1
represents the name of the first range (R IC I: R7C5).
Name2
represents the
name of the second range (R4C3: R II C7). The names of the two
intersecting ranges are separated by a blank space.

U sing cell groups is similar to using references to individual cells. For
instance, suppose you want to add the values in the two ranges (the union)
in the example above. You could type:
SUM (RIC!: R7C5,R4C3: RIIC7)
Notice however, that because the two ranges in the union intersect
(overlap), the values in the intersection would be counted twice. To correct
this problem, subtract the intersection:
SUM (RICI: R7C5, R4C3: RIIC7)- SUM
(name1 name2)
Note also that, after you name the two ranges, you can use the range names
in the first part of the formula to denote the union:
SUM
(name
1,
name2) -
SUM
(name
1
name2)
