The product of any number x and 1 is always x.
Reciprocals, like 2 and 1/2, have a product of 1.
The number you multiplied by 1.
10. The product of 1 and any other number, x, is x.
The product would be 1, unless the number is zero in which case there is no solution because no number can be multiplied by zero and equal 1.
No. The identity for multiplication is the number 1. If you multiply a number by 1, then the product is the original number. If you multiply a number by zero, the product is zero, so the number has 'lost it's identity'
