@pkjag Do not give out direct answers without explanation.

1 is obviously the 0 property of multiplication. If you multiply any number by 0 the result is always 0. 2 is obviously the reciprocal property of multiplication. If you multiply a number by its reciprocal the result is 1. 3 is obviously the -1 property of multiplication. When you multiply a number by -1, you just switch the sign. 4 is obviously the -1 property of division. When you divide a number by -1, you just switch the sign.
