OK, let's work through this together. We're starting with 711 and we're going to multiply it by 34, which means we add 711 to itself 34 times.
Step 1: 0 + 711 = 711
Step 2: 711 + 711 = 1422
Step 3: 1422 + 711 = 2133
Step 4: 2133 + 711 = 2844
Step 5: 2844 + 711 = 3555
Step 6: 3555 + 711 = 4266
Step 7: 4266 + 711 = 4977
Step 8: 4977 + 711 = 5688
Step 9: 5688 + 711 = 6399
Step 10: 6399 + 711 = 7110
Step 11: 7110 + 711 = 7821
Step 12: 7821 + 711 = 8532
Step 13: 8532 + 711 = 9243
Step 14: 9243 + 711 = 9954
Step 15: 9954 + 711 = 10665
Step 16: 10665 + 711 = 11376
Step 17: 11376 + 711 = 12087
Step 18: 12087 + 711 = 12798
Step 19: 12798 + 711 = 13509
Step 20: 13509 + 711 = 14220
Step 21: 14220 + 711 = 14931
Step 22: 14931 + 711 = 15642
Step 23: 15642 + 711 = 16353
Step 24: 16353 + 711 = 17064
Step 25: 17064 + 711 = 17775
Step 26: 17775 + 711 = 18486
Step 27: 18486 + 711 = 19197
Step 28: 19197 + 711 = 19908
Step 29: 19908 + 711 = 20619
Step 30: 20619 + 711 = 21330
Step 31: 21330 + 711 = 22041
Step 32: 22041 + 711 = 22752
Step 33: 22752 + 711 = 23463
Step 34: 23463 + 711 = 24174

So, 711*34 = 24174
