Let's roll up our sleeves and solve this. We have 598 and we're going to multiply it by 28, essentially adding 598 to itself 28 times.
Step 1: 0 + 598 = 598
Step 2: 598 + 598 = 1196
Step 3: 1196 + 598 = 1794
Step 4: 1794 + 598 = 2392
Step 5: 2392 + 598 = 2990
Step 6: 2990 + 598 = 3588
Step 7: 3588 + 598 = 4186
Step 8: 4186 + 598 = 4784
Step 9: 4784 + 598 = 5382
Step 10: 5382 + 598 = 5980
Step 11: 5980 + 598 = 6578
Step 12: 6578 + 598 = 7176
Step 13: 7176 + 598 = 7774
Step 14: 7774 + 598 = 8372
Step 15: 8372 + 598 = 8970
Step 16: 8970 + 598 = 9568
Step 17: 9568 + 598 = 10166
Step 18: 10166 + 598 = 10764
Step 19: 10764 + 598 = 11362
Step 20: 11362 + 598 = 11960
Step 21: 11960 + 598 = 12558
Step 22: 12558 + 598 = 13156
Step 23: 13156 + 598 = 13754
Step 24: 13754 + 598 = 14352
Step 25: 14352 + 598 = 14950
Step 26: 14950 + 598 = 15548
Step 27: 15548 + 598 = 16146
Step 28: 16146 + 598 = 16744

So, 598*28 = 16744
