Sure thing, let's get straight to it. We start with 428 and we're going to multiply it by 9, which means adding 428 to itself 9 times.
Step 1: 0 + 428 = 428
Step 2: 428 + 428 = 856
Step 3: 856 + 428 = 1284
Step 4: 1284 + 428 = 1712
Step 5: 1712 + 428 = 2140
Step 6: 2140 + 428 = 2568
Step 7: 2568 + 428 = 2996
Step 8: 2996 + 428 = 3424
Step 9: 3424 + 428 = 3852

So, 428*9 = 3852
