Let's roll up our sleeves and solve this. We have 245 and we're going to multiply it by 22, essentially adding 245 to itself 22 times.
Step 1: 0 + 245 = 245
Step 2: 245 + 245 = 490
Step 3: 490 + 245 = 735
Step 4: 735 + 245 = 980
Step 5: 980 + 245 = 1225
Step 6: 1225 + 245 = 1470
Step 7: 1470 + 245 = 1715
Step 8: 1715 + 245 = 1960
Step 9: 1960 + 245 = 2205
Step 10: 2205 + 245 = 2450
Step 11: 2450 + 245 = 2695
Step 12: 2695 + 245 = 2940
Step 13: 2940 + 245 = 3185
Step 14: 3185 + 245 = 3430
Step 15: 3430 + 245 = 3675
Step 16: 3675 + 245 = 3920
Step 17: 3920 + 245 = 4165
Step 18: 4165 + 245 = 4410
Step 19: 4410 + 245 = 4655
Step 20: 4655 + 245 = 4900
Step 21: 4900 + 245 = 5145
Step 22: 5145 + 245 = 5390

So, 245*22 = 5390
