And the sum or both play the role of connecting the two conditions, thus forming a big condition. Their difference is:

1 and "and" mean that only when two conditions are met can they be considered as meeting the main conditions.

Such as: 0

For example:

X=0 can only satisfy the second condition, but can't satisfy the first condition, so it can't satisfy the big condition;

X= 1 can satisfy both the second condition and the major condition;

X=4 can only satisfy the first condition, but can't satisfy the second condition, so it can't satisfy the big condition;

X= 10 cannot satisfy both the second condition and the first condition, so it cannot satisfy the big condition;

So, 0

2. "Or" means that as long as either of the two conditions can be met, it is considered that the major condition is met.

Such as: 0

For example:

X=0 can satisfy the second condition, that is to say, it can satisfy the big condition;

X= 1 can satisfy both the second condition and the major condition.

X=4 can satisfy the first condition, so it can also satisfy the big condition;

X= 10 cannot satisfy both the second condition and the first condition, so it cannot satisfy the big condition;

So, 0
