Twenty-one fish are swimming in an aquarium. eleven are removed, leaving 10 fish. which number is the additive inverse of the number of fish left? a) −10 b) −11 c) −21 d) 10

The additive inverse: The usage of addition with a negative number.

The original equation is 21 - 11 = 10

To use the additive inverse, change it so that there is an addition sign.

21 + (-11) = 10

B) -11 is your answer

hope this helps
