	In the 
	formulae  1 
	+ 2 = 3 :  1 
	and 
	2 
	are called 
	addends 
	or 
	terms, 
	while 
	3 
	is called the 
	sum. 
	
	With the 
	commutative property of addition 
	, the order we add two numbers does not 
	matter. eg. 1+2 = 2+1. 
	
	With the 
	associative property of addition 
	, the order we add three numbers does not 
	matter. eg. (1+2)+3 = 1+(2+3) since we will always get the same result on 
	both sides. 
	
	The 
	addition property of 0 
	 states that adding 0 to any number 
	results in the same number. 
	eg. 6 + 0 = 6. 
	
	In the formulae  3 
	- 2 = 1:  3 
	is the 
	minuend 
	 , 
	2 
	is the 
	subtrahend 
	and 
	1 
	is the 
	difference. 
	
	In the formulae  3 
	+ 2 = 6 :  3 
	and 
	2 
	are called 
	factors 
	, while 
	6 
	is called the 
	product. 
	
	With the 
	commutative property of multiplication 
	, the order in which we multiply two numbers does not matter. eg. 3 * 2 = 2 
	* 3 . 
  
	
	With the 
	associative property of multiplication 
	, the order we multiply three numbers does not matter. eg. (2*3)*4 = 2*(3*4) 
	since we will always get the same result on both sides. 
	
	The 
	multiplication property of 0 
	 states that multiplying any number by 0 
	results with 0 . 
	eg. 6 * 0 = 0 . 
	
	In the formulae  6 
	divided 2 = 3 :  6 
	is the 
	dividend 
	 , 
	2 
	is the 
	divisor 
	 and 
	3 
	is the 
	quotient . 
	
	The 
	division property of 0 
	 states 
	that 0 divided by any number (except 0 ) results in 0. 
	
	also if any number (including 0) is divided 
	by zero, the result is undefined (or infinity) .
