Let's get this math done. We have 302 and we're going to multiply it by 22. This is the same as taking 302 and adding it to itself 22 times.
Step 1: 0 + 302 = 302
Step 2: 302 + 302 = 604
Step 3: 604 + 302 = 906
Step 4: 906 + 302 = 1208
Step 5: 1208 + 302 = 1510
Step 6: 1510 + 302 = 1812
Step 7: 1812 + 302 = 2114
Step 8: 2114 + 302 = 2416
Step 9: 2416 + 302 = 2718
Step 10: 2718 + 302 = 3020
Step 11: 3020 + 302 = 3322
Step 12: 3322 + 302 = 3624
Step 13: 3624 + 302 = 3926
Step 14: 3926 + 302 = 4228
Step 15: 4228 + 302 = 4530
Step 16: 4530 + 302 = 4832
Step 17: 4832 + 302 = 5134
Step 18: 5134 + 302 = 5436
Step 19: 5436 + 302 = 5738
Step 20: 5738 + 302 = 6040
Step 21: 6040 + 302 = 6342
Step 22: 6342 + 302 = 6644

So, 302*22 = 6644
