If E = {even integers}, then insert the appropriate symbol `in` or `cancel(in)` in the blanks :
-4,12 . . . . . . . E

Answer

To solve the question, we need to determine whether the numbers -4 and 12 belong to the set of even integers, denoted by E.

### Step-by-Step Solution:

1. **Understand the Set E**:
The set E is defined as the set of all even integers. Even integers are numbers that can be divided by 2 without leaving a remainder.

2. **Check the First Number (-4)**:
- We need to check if -4 is an even integer.
- To do this, we divide -4 by 2:
\[ -4 \div 2 = -2 \]
- Since -2 is an integer and there is no remainder, -4 is an even integer.

3. **Check the Second Number (12)**:
- Now, we check if 12 is an even integer.
- We divide 12 by 2:
\[ 12 \div 2 = 6 \]
- Since 6 is an integer and there is no remainder, 12 is also an even integer.

4. **Conclusion**:
- Since both -4 and 12 are even integers, we conclude that both numbers belong to the set E.
- Therefore, we fill in the blanks with the symbol "in" for both numbers.

### Final Answer:
-4 **in** E
12 **in** E
