Subtract two table with condition

[tejapowerbi123]

Hello Community
I am trying to subtract the "No" column (Table 2) from to "No" column (Table 1) and want to display the result by the "Name" column.
I have tried using UNION and SUMMARIZEDCOLUMNS, but it is not showing me the correct result.
Can someone help me?

Table 1
Name	No
A	1
A	2
B	3
B	1
C	2
C	3

Table 2
Name	No
A	2
B	3
C	4
A	4
A	2
A	2

Expected Result
Name	No
A	7
B	-1
C	-1

Expanded table, bridge table or disconnected table are all methods to tackle such a simple question.
