Sure thing! We've got 298 and we're gonna multiply it by 28. That's the same as adding 298 to itself 28 times.
Step 1: 0 + 298 = 298
Step 2: 298 + 298 = 596
Step 3: 596 + 298 = 894
Step 4: 894 + 298 = 1192
Step 5: 1192 + 298 = 1490
Step 6: 1490 + 298 = 1788
Step 7: 1788 + 298 = 2086
Step 8: 2086 + 298 = 2384
Step 9: 2384 + 298 = 2682
Step 10: 2682 + 298 = 2980
Step 11: 2980 + 298 = 3278
Step 12: 3278 + 298 = 3576
Step 13: 3576 + 298 = 3874
Step 14: 3874 + 298 = 4172
Step 15: 4172 + 298 = 4470
Step 16: 4470 + 298 = 4768
Step 17: 4768 + 298 = 5066
Step 18: 5066 + 298 = 5364
Step 19: 5364 + 298 = 5662
Step 20: 5662 + 298 = 5960
Step 21: 5960 + 298 = 6258
Step 22: 6258 + 298 = 6556
Step 23: 6556 + 298 = 6854
Step 24: 6854 + 298 = 7152
Step 25: 7152 + 298 = 7450
Step 26: 7450 + 298 = 7748
Step 27: 7748 + 298 = 8046
Step 28: 8046 + 298 = 8344

So, 298*28 = 8344
