What two simpler problems can you use to find 4x22?
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. :-)
