2. Simplifying expressions
When multiplying pronumerals, remember that order is not important.
3 × 6 = 6 × 3
6 × w = w × 6
a × b = b × a
Also keep in mind that the multiplication sign (×) is usually left out:
3 × g × h = 3gh
2 × x2 × y = 2x2y
Although order is not important, the pronumerals in each term are usually written in alphabetical order.
2 × b2 × a × c = 2ab2c.
