Jharne De and Ranjana Kumar Solutions for Chapter: Natural Numbers and Whole Numbers, Exercise 2: Revision Exercise

 Identify the property as commutative, associative, or distributive.

 $$\begin{gathered} \mathrm{a}\times (\mathrm{b}+\mathrm{c})=(\mathrm{a}\times \mathrm{b})+(\mathrm{a}\times \mathrm{c}) \\ \mathrm{a}\times (\mathrm{b}-\mathrm{c})=(\mathrm{a}\times \mathrm{b})-(\mathrm{a}\times \mathrm{c}) \end{gathered}$$

  Rewrite using the commutative property  $\mathrm{x}+\mathrm{y}$

Rewrite using the associative property $7\left(\mathrm{ab}\right)$

Rewrite using the distributive property $5(\mathrm{a}+\mathrm{b})$
