Let's get this math done. We have 364 and we're going to multiply it by 7. This is the same as taking 364 and adding it to itself 7 times.
Step 1: 0 + 364 = 364
Step 2: 364 + 364 = 728
Step 3: 728 + 364 = 1092
Step 4: 1092 + 364 = 1456
Step 5: 1456 + 364 = 1820
Step 6: 1820 + 364 = 2184
Step 7: 2184 + 364 = 2548

So, 364*7 = 2548
