elementary number theory - Multiplicative inverse of $3

WebFor example, with whole numbers, 15 is equivalent to 15/1 (15 over 1). To get that, you multiply by the multiplicative inverse of 15 - in this case, 1/15, by the original number, getting 1. Swapping the numerator and the denominator is the same concept. So for 4/5 (4 over 5), you would multiply it by 5/4 (5 over 4).

WebIn a ring, multiplicative inverses are not required to exist. A nonzero commutative ring in which every nonzero element has a multiplicative inverse is called a field. The additive group of a ring is the underlying set equipped with only the operation of addition. WebFollow the steps given below to find the multiplicative inverse of a complex number a + ib: Step 1: Write the reciprocal in the form of 1/ (a+ib). Step 2: Multiply and divide this number by the conjugate of (a+ib). Step 3: Apply the following formulae: (a + b) (a - b) = a 2 - b 2, and i 2 = -1. Step 4: Simplify to the lowest form.

Consider Z / 5 Z with multiplication, which can be thought of as { 0, 1, 2, 3, 4 } with the usual multiplication, but take the result mod 5. So, for example, 2 ∗ 3 = 1. Therefore, the inverse of 2 in Z / 5 Z is 3.
