Sure thing, let's get straight to it. We start with 784 and we're going to multiply it by 10, which means adding 784 to itself 10 times.
Step 1: 0 + 784 = 784
Step 2: 784 + 784 = 1568
Step 3: 1568 + 784 = 2352
Step 4: 2352 + 784 = 3136
Step 5: 3136 + 784 = 3920
Step 6: 3920 + 784 = 4704
Step 7: 4704 + 784 = 5488
Step 8: 5488 + 784 = 6272
Step 9: 6272 + 784 = 7056
Step 10: 7056 + 784 = 7840

So, 784*10 = 7840
