Line 1:
Line 1: − + − − Examples: − − 3 + 2 = 5 the order of the operands doesnt matter 3 + 2 = 2 + 3 = 5 <br> − for larger numbers they are added in order of smallest unit to largest unit<br> − 17 + 25 = 42 add the units 5 + 7 = 12 add the tens 10 + 20 = 30 then add them 12 + 30 = 42
move to talk, and italicize variables for clarity
'''Addition''' is the name given to the [[mathematical]] [[function]] which involves the combination of two values, resulting in a directly related linear increase. The sum a + b can be interpreted as a [[binary]] operation that combines a and b, in an algebraic sense, or it can be interpreted as the addition of c more units to b. Under the latter interpretation, the parts of a sum c + a play [[symmetric]] roles, and the operation a + c is viewed as applying the [[unary]] operation +b to a. Instead of calling both a and b [[addend]]s, it is more appropriate to call a the augend in this case, since a plays a passive role. The unary view is also useful when discussing [[subtraction]], because each unary addition operation has an [[inverse operations|inverse]] unary subtraction operation and vice versa.
