Sure thing, let's get straight to it. We start with 107 and we're going to multiply it by 7, which means adding 107 to itself 7 times.
Step 1: 0 + 107 = 107
Step 2: 107 + 107 = 214
Step 3: 214 + 107 = 321
Step 4: 321 + 107 = 428
Step 5: 428 + 107 = 535
Step 6: 535 + 107 = 642
Step 7: 642 + 107 = 749

So, 107*7 = 749
