Deductive reasoning (top down) is when you use a rule to form a conclusion. For example, a rule could be A=B. So, if you see an A, the conclusion is that it is also B.
Inductive reasoning (bottom up) is when you use a conclusion to create a rule. So, let’s say you examine a bunch of A’s, and by observation realize that they are also B. With that info, you theorize that A=B.
The terms bottom/top up refer to how the conclusion relates to the rule. The rule is on top, the conclusion is on the bottom. When use a rule to determine the conclusion, that is from top to bottom (deductive). When you use a conclusion to make the rule, you are going from bottom to top (inductive).
