OK, let's work through this together. We're starting with 246 and we're going to multiply it by 7, which means we add 246 to itself 7 times.
Step 1: 0 + 246 = 246
Step 2: 246 + 246 = 492
Step 3: 492 + 246 = 738
Step 4: 738 + 246 = 984
Step 5: 984 + 246 = 1230
Step 6: 1230 + 246 = 1476
Step 7: 1476 + 246 = 1722

So, 246*7 = 1722
