📘 Worked solution
131 = 30 + 1, 34 = 30 + 4Split each factor into tens and ones.
230 · 30 = 900, 30 · 4 = 120, 1 · 30 = 30, 1 · 4 = 4Multiply each pair of parts -- these are the four smaller rectangles in the area model.
3900 + 120 + 30 + 4 = 1054Add the four partial products together to get the final answer.
