Let's roll up our sleeves and solve this. We have 65 and we're going to multiply it by 28, essentially adding 65 to itself 28 times.
Step 1: 0 + 65 = 65
Step 2: 65 + 65 = 130
Step 3: 130 + 65 = 195
Step 4: 195 + 65 = 260
Step 5: 260 + 65 = 325
Step 6: 325 + 65 = 390
Step 7: 390 + 65 = 455
Step 8: 455 + 65 = 520
Step 9: 520 + 65 = 585
Step 10: 585 + 65 = 650
Step 11: 650 + 65 = 715
Step 12: 715 + 65 = 780
Step 13: 780 + 65 = 845
Step 14: 845 + 65 = 910
Step 15: 910 + 65 = 975
Step 16: 975 + 65 = 1040
Step 17: 1040 + 65 = 1105
Step 18: 1105 + 65 = 1170
Step 19: 1170 + 65 = 1235
Step 20: 1235 + 65 = 1300
Step 21: 1300 + 65 = 1365
Step 22: 1365 + 65 = 1430
Step 23: 1430 + 65 = 1495
Step 24: 1495 + 65 = 1560
Step 25: 1560 + 65 = 1625
Step 26: 1625 + 65 = 1690
Step 27: 1690 + 65 = 1755
Step 28: 1755 + 65 = 1820

So, 65*28 = 1820
