Explain what the Multiplicative Identity is and give an example. (2 points)
The multiplicative identity refers to the number that, when multiplied by any other number, gives the same number as the result. In other words, it is the number that does not alter the value of the other number in a multiplication operation.
The multiplicative identity is represented by the number 1. When any number is multiplied by 1, the result is that number. For example, if we multiply 7 by 1, the result is 7: 7 x 1 = 7. Similarly, if we multiply 0.5 by 1, the result is 0.5: 0.5 x 1 = 0.5. Therefore, 1 acts as the multiplicative identity for all numbers in multiplication operations.
