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. :-)
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
38*10-38 or 9*40-9*2. The answer of that is 342, if you haven't figured it out yet.
7x38=266 7x8=56 +7x3=21= 210 because the 3 is in the 10 position so you add a 0 on the end.
