Sure thing, let's get straight to it. We start with 887 and we're going to multiply it by 7, which means adding 887 to itself 7 times.
Step 1: 0 + 887 = 887
Step 2: 887 + 887 = 1774
Step 3: 1774 + 887 = 2661
Step 4: 2661 + 887 = 3548
Step 5: 3548 + 887 = 4435
Step 6: 4435 + 887 = 5322
Step 7: 5322 + 887 = 6209

So, 887*7 = 6209
