Conclusion

In this chapter, you have reviewed basic number systems and some of the properties relating to them. In addition to the commutative, associative, and distributive properties of numbers, you have explored the additive and multiplicative identities and inverses of numbers. Also, you have investigated how use of different combinations of positive and negative values influences the outcome of operations. Such activities have immediate applications when you work with exponents, scientific notation, and root and radical expressions, which are topics of the next chapter.
