what‘s the meaning of inference

Inferences are steps in reasoning, 
	moving from premises to logical consequences; 
	
etymologically, 
	the word infer means to "carry forward". 
	
Inference is theoretically traditionally divided into deduction and induction,
	a distinction that in Europe dates 
		at least to Aristotle (300s BCE). 
	Deduction is inference 
		deriving logical conclusions from premises known or assumed to be true, 
			with the laws of valid inference being studied in logic. 
	Induction is inference 
		from particular evidence to a universal conclusion
