Finding an additive inverse is a simple 1-step procedure: . For Fractions
The additive inverse of a number is its . When you add a number to its additive inverse, the result is always zero . Core Concept additive inverse
The numerical values of the numerator and denominator do not change. Only the sign of the entire fraction flips. The inverse of 23two-thirds −23negative two-thirds The inverse of −59negative five-nineths 59five-nineths For Algebraic Expressions Finding an additive inverse is a simple 1-step procedure:
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 Core Concept The numerical values of the numerator
To find the inverse of an expression, multiply the entire thing by -1negative 1 or flip the sign of every term. : Inverse : Practical Applications
