Not sure exactly what you mean, but i’ll go from what I assume this means.
Subtraction:
[any number minus itself equals 0]
0 - 0 = 0
1 - 1 = 0
2 - 2 = 0
3 - 3 = 0
4 - 4 = 0
5 - 5 = 0
6 - 6 = 0
7 - 7 = 0
8 - 8 = 0
9 - 9 = 0
Addition:
0 + 0 = 0
Multiplication:
[Any number times 0 equals 0]
0 x 0 = 0
1 x 0 = 0
2 x 0 = 0
all the way to 9
Division:
[any number divided by 0 equals 0]
0 / 0 = 0
1 / 0 = 0
2 / 0 = 0
3 / 0 = 0
all the way to 9
