Let's roll up our sleeves and solve this. We have 760 and we're going to multiply it by 19, essentially adding 760 to itself 19 times.
Step 1: 0 + 760 = 760
Step 2: 760 + 760 = 1520
Step 3: 1520 + 760 = 2280
Step 4: 2280 + 760 = 3040
Step 5: 3040 + 760 = 3800
Step 6: 3800 + 760 = 4560
Step 7: 4560 + 760 = 5320
Step 8: 5320 + 760 = 6080
Step 9: 6080 + 760 = 6840
Step 10: 6840 + 760 = 7600
Step 11: 7600 + 760 = 8360
Step 12: 8360 + 760 = 9120
Step 13: 9120 + 760 = 9880
Step 14: 9880 + 760 = 10640
Step 15: 10640 + 760 = 11400
Step 16: 11400 + 760 = 12160
Step 17: 12160 + 760 = 12920
Step 18: 12920 + 760 = 13680
Step 19: 13680 + 760 = 14440

So, 760*19 = 14440
