Let's get this math done. We have 369 and we're going to multiply it by 7. This is the same as taking 369 and adding it to itself 7 times.
Step 1: 0 + 369 = 369
Step 2: 369 + 369 = 738
Step 3: 738 + 369 = 1107
Step 4: 1107 + 369 = 1476
Step 5: 1476 + 369 = 1845
Step 6: 1845 + 369 = 2214
Step 7: 2214 + 369 = 2583

So, 369*7 = 2583
