And alsoWhich two integers are their own multiplicative inverse
answer mine and I'll answer yours
1?1=1. (-1)(-1)=1. So 1 and -1 are their own multiplicative inverse.
An additive inverse of a number is a number that when added to the original number gives the identity element. The identity under addition is the single number that when added to any other number gives that other number. It is similar for the multiplicative inverse and identity. The identity under addition is 0 and under multiplication it is 1. Therefore to solve this use these equations: x+x=0 and x*x=1 x?=1 So solving these equations will get the answers. 2x=0, x=0 So 0 is it's own additive inverse, x?=1, x=1 or -1 So 1 and -1 are both their own multiplicative inverse.
