Let's roll up our sleeves and solve this. We have 448 and we're going to multiply it by 30, essentially adding 448 to itself 30 times.
Step 1: 0 + 448 = 448
Step 2: 448 + 448 = 896
Step 3: 896 + 448 = 1344
Step 4: 1344 + 448 = 1792
Step 5: 1792 + 448 = 2240
Step 6: 2240 + 448 = 2688
Step 7: 2688 + 448 = 3136
Step 8: 3136 + 448 = 3584
Step 9: 3584 + 448 = 4032
Step 10: 4032 + 448 = 4480
Step 11: 4480 + 448 = 4928
Step 12: 4928 + 448 = 5376
Step 13: 5376 + 448 = 5824
Step 14: 5824 + 448 = 6272
Step 15: 6272 + 448 = 6720
Step 16: 6720 + 448 = 7168
Step 17: 7168 + 448 = 7616
Step 18: 7616 + 448 = 8064
Step 19: 8064 + 448 = 8512
Step 20: 8512 + 448 = 8960
Step 21: 8960 + 448 = 9408
Step 22: 9408 + 448 = 9856
Step 23: 9856 + 448 = 10304
Step 24: 10304 + 448 = 10752
Step 25: 10752 + 448 = 11200
Step 26: 11200 + 448 = 11648
Step 27: 11648 + 448 = 12096
Step 28: 12096 + 448 = 12544
Step 29: 12544 + 448 = 12992
Step 30: 12992 + 448 = 13440

So, 448*30 = 13440
