2 Combine Universal Positive statement with Universal Negative will give Universal Negative Conclusion

A+ E= E

Statement:

No Rats are Bats

Conclusion:

No Cars are Bats

3 Combine E + A= O Reverse

Rules-
1) If Statement is Positive then Conclusion must be Positive

Example:
Statement- All pens are pencils

2) If Statement is Negative then Conclusion must be Negative
Example:
Statement- No Pens are Pencils

3) +ve plus +ve = positive Conclusion
+ve plus -ve = Negative Conclusion
-ve plus -ve = No Conclusion eg. O+ O= No conclusion

Steps:

1 Choose Statements

If Subject and predicate are in one statements then – Immediate Inference

If Subject and predicate are in Different statements then – Mediate Inference

2 Check alignment:

To merge Questions Common term should be predicate in first statement and Subject in Second statement in this case we change Order or Convert on the bases of IEA or Do Both as per situation

Example: Statement:

All Cars are Rats

All Vans are Cars

Conclusion:

All Vans are Rats

Example: Statement:

Some Cars are Rats

All Vans are Rats

3 Check If conclusion Follows

one statements then – Immediate Inference

More statements then – Mediate Inference

4 Check Complimentary Pairs– Conclusion Either or

Square of Opposition

Example if given is true then which of following is true

Contradictories: A and O, E and I

A and O Both cannot be true or false together means if one is false then other must be true
