OK, let's work through this together. We're starting with 122 and we're going to multiply it by 7, which means we add 122 to itself 7 times.
Step 1: 0 + 122 = 122
Step 2: 122 + 122 = 244
Step 3: 244 + 122 = 366
Step 4: 366 + 122 = 488
Step 5: 488 + 122 = 610
Step 6: 610 + 122 = 732
Step 7: 732 + 122 = 854

So, 122*7 = 854
