multiply math rule

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 * 9) = 900-99

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 :)
