is allowed when the bill 4a * 5 20a count or is that not allowed?

yeah does it work you may thus multiply but not add

Yes, you can do. 4a * 5 = 4 * a *. 5 That you can switch to 4 * 5 * a. 4 * 5 = 20, so you can also write short 20a.

can you do

Vertauschungsgesetz (commutative)

*For multiplication, we must reverse the order of the factors required.* *The result does not change this.* **(For division we must not, of course!).**

2 * 5 = 5 * 2

Compound Act (associative law)

*For multiplication, we must the factors summarized as desired (by parentheses).* *The result does not change this.* *(For division we must not, of course!).*

(8 * 5) * 4 = 8 * (5 * 4)

Distribution law (distributive)

One must, if possible, and'einklammern''ausklammern'!

**27 * 97 + 27 * 3 =** 27 * (97 + 3) = 27 * 100

(100 - ** 11) * 9 = (100 *** 9) - (11 *

clearly this is allowed ... 4 * 5 = 20a, 4a * 5b = 20ab

Kommuntativgesetz: 4 * A * 5 = 4 * 5 * 20 * a = A = 20a. Hope I could help you, six- oedr Seniors / in :)
