What thought process would you use when trying to find the additive or multiplication inverse of a number or expression?
Additive inverse: change all signs. Multiplicative inverse: flip it over.
What is the additive inverse of a over 3?
It is -a/3
Multiplicative inverse of -3?
The multiplicative inverse of -3 is -(1/3) or negative one-third. The multiplicative inverse of a number is the number that you multiply it by to get a result of 1 (the multiplicative identity). So, since -3 times -(1/3) is 1, -(1/3) is the multiplicative inverse of -3. Similarly, +3 is the ADDITIVE inverse of -3. The additive inverse of a number is the number you add to it to get a result of 0 (the additive identity). So, since -3 + (+3) = 0, +3 is the additive inverse of -3. The original answer given here was that the multiplicative inverse of -3 is +3, which is flat incorrect.
What is the additive inverse of -2 over -3?
-5
What is the additive inverse of 1 over 4?
-1/4
What is the additive inverse of 1 over 2?
-1/2
What is the additive inverse of fraction -4 over 7?
4/7
What is the additive inverse of 3 over 4?
Oh, dude, the additive inverse of 3 over 4 is -3 over 4. It's like flipping the sign of the fraction, you know? So, if you owed someone 3/4 of a pizza, the additive inverse would mean you now have 3/4 of a pizza. Cool, right?
What is the additive inverse of negative seven over nine?
+7/9, positive seven over nine.
Whats the Multiplicative Inverse of negative fifteen and two thirds?
If the multiplicative inverse of a number is the number that you could multiply with the original number in order to obtain one, then the mulitplicative inverse of -15 and 2/3 is -3/47 negative three fourtysevenths, or negative three over fourtyseven.
What is the inverse of 10?
the inverse of any number is the fraction of ONE over that number. so, inverse of ten is ONE/TEN or one tenth. the inverse of 3 is ONE/THREE or one third the inverse of one fourth is a bit trickier, but not if you go slowly, ONE over ONE FOURTH, which mathematically changes to 4. the inverse of cat is ONE over CAT (which is senseless, but might help you remember how to do inverses).
What does inverse mean in mathematics?
It depends on the context. The additive inverse of a number, X, is the number -X such that their sum is 0. The multiplicative inverse of a (non-zero) number, Y, is the number -Y such that their product is 1. The inverse of a function f, is the function g (over appropriate domains and ranges) such that if f(X) = Y then g(Y) = X. So, for example, if f(X) = 2X then g(X) = X/2 or if f(X) = exp(X) then g(X) = ln(X), and so on.
