1) 9x3 = 3x3x3 (but that's not really simpler?)
How about 1) 9+9+9, and 2) 3+3+3+3+3+3+3+3+3?
#2 doesn't look too simple either. How about 9x3 = (10-1)x3 = 10x3-1x3 = 30-3 = 27? That one's nice.

Two simpler problems? It's not clear what this means.Maybe 2x44 or 8x11? - but they're not really simpler.Maybe (2x2)(2x11), but that doesn't get you closer to the answer.Maybe 4x20=80, 4x2=8 and 80+8=88 - but that's 3 simpler problems.If this is not your question, please clarify and ask the question again. :-)
To find 42 x 56, you can break it down into simpler problems using the distributive property. First, you can calculate 40 x 56, which is 2240. Then, find 2 x 56, which equals 112. Finally, add these two results together: 2240 + 112 = 2352. Thus, 42 x 56 = 2352.
38*10-38 or 9*40-9*2. The answer of that is 342, if you haven't figured it out yet.

7 times thirty plus 7 times 8 = 210+56=266
9x3-5+2
22 * 2 =44 44 * 2 = 88 Partitioning 22 is not an option since that leads to 3 problems, not 2: 4 * 20 = 80 4 * 2 = 8 and 80 + 8 = 88
7x38=266 7x8=56 +7x3=21= 210 because the 3 is in the 10 position so you add a 0 on the end.
Either.However, if you know two sides and the includedangle then the sine rule is simpler.
No, it is simpler than that. Simply add the two magnitudes. The direction will be the same as the parallel vectors.

The only possibility is to produce its two constituent elements.
