5		461				1,095				10				784				766

a. Calculate cumulative breadth. (Negative amounts should be indicated by a minus sign.)

Day        Advances            Declines              Net Advances            Cumulative Breadth

1             1,041                    1,004                 

2             833                        1,000                 

3             721                        1,059                 

4             773                        1,508                 

5             461                        1,095

9             1,120                     918                   

10          784                         766                   

Answer 1

Days	Advances (A)	Declines (D)	Net Advances (A-D)	Cumulative Breadth
1	1,041	1,004	37	37
2	833	1,000	-167	-130
3	721	1,059	-338	-468
4	773	1,508	-735	-1,203
5	461	1,095	-634	-1,837
6	988	882	106	-1,731
7	1,182	1,149	33	-1,698
8	939	722	217	-1,481
9	1,120	918	202	-1,279
10	784	766	18	-1,261

Cumulative breadth = yesterday's cumulative breadth + today's net advances
