Let's roll up our sleeves and solve this. We have 760 and we're going to multiply it by 34, essentially adding 760 to itself 34 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
Step 20: 14440 + 760 = 15200
Step 21: 15200 + 760 = 15960
Step 22: 15960 + 760 = 16720
Step 23: 16720 + 760 = 17480
Step 24: 17480 + 760 = 18240
Step 25: 18240 + 760 = 19000
Step 26: 19000 + 760 = 19760
Step 27: 19760 + 760 = 20520
Step 28: 20520 + 760 = 21280
Step 29: 21280 + 760 = 22040
Step 30: 22040 + 760 = 22800
Step 31: 22800 + 760 = 23560
Step 32: 23560 + 760 = 24320
Step 33: 24320 + 760 = 25080
Step 34: 25080 + 760 = 25840

So, 760*34 = 25840
