Finding an additive inverse is a simple 1-step procedure: . For Fractions
: Used to "zero out" constants to isolate variables (e.g., subtracting from both sides of
The states that for any real number , there exists a number −anegative a such that: a+(−a)=0a plus open paren negative a close paren equals 0 Positive numbers : The inverse is negative (e.g., 8→-88 right arrow negative 8 Negative numbers : The inverse is positive (e.g., -12→12negative 12 right arrow 12 Zero : The only number that is its own additive inverse ( How to Find It
Do not confuse the with the multiplicative inverse (reciprocal). Additive Inverse Multiplicative Inverse Goal Product of Action Change the sign Flip the fraction Example (for 5) -5negative 5 15one-fifth Additive Inverse 127-3.3
