Btw I think you're not correct about the 8 digit multiplication. I tried: please could you multiply 12345678 by 87654321. Give your answer in steps. Each step should calculate one column at a time from right to left remembering to carry any digits which overflowed in a previous step. At the end add a final step adding the values up. And it gave me the following, which I believe to be correct: Sure, I'll be doing a long multiplication here, step by step, column by column from right to left. For brevity, I'll write the numbers to be multiplied as: A: 12345678 B: 87654321 Step 1: Multiply the 1st digit of B by A: 1 * 12345678 = 12345678 Step 2: Multiply the 2nd digit of B by A, remember to shift one position to the left: 2 * 12345678 = 24691356 (shift one position to the left, i.e., append a 0 at the end) Step 3: Multiply the 3rd digit of B by A, remember to shift two positions to the left: ... skip some of the answer because you get the gist.... 7 * 12345678 = 86419746 (shift six positions to the left, i.e., append six 0s at the end) Step 8: Multiply the 8th digit of B by A, remember to shift seven positions to the left: 8 * 12345678 = 98765424 (shift seven positions to the left, i.e., append seven 0s at the end) Now, the last step is to add all these results together: 12345678 246913560 3703703400 49382712000 617283900000 7407406800000 86419746000000 987654240000000 = 1082152022374638 So, the result of 12345678 multiplied by 87654321 is 1082152022374638.
