OK, let's work through this together. We're starting with 960 and we're going to multiply it by 34, which means we add 960 to itself 34 times.
Step 1: 0 + 960 = 960
Step 2: 960 + 960 = 1920
Step 3: 1920 + 960 = 2880
Step 4: 2880 + 960 = 3840
Step 5: 3840 + 960 = 4800
Step 6: 4800 + 960 = 5760
Step 7: 5760 + 960 = 6720
Step 8: 6720 + 960 = 7680
Step 9: 7680 + 960 = 8640
Step 10: 8640 + 960 = 9600
Step 11: 9600 + 960 = 10560
Step 12: 10560 + 960 = 11520
Step 13: 11520 + 960 = 12480
Step 14: 12480 + 960 = 13440
Step 15: 13440 + 960 = 14400
Step 16: 14400 + 960 = 15360
Step 17: 15360 + 960 = 16320
Step 18: 16320 + 960 = 17280
Step 19: 17280 + 960 = 18240
Step 20: 18240 + 960 = 19200
Step 21: 19200 + 960 = 20160
Step 22: 20160 + 960 = 21120
Step 23: 21120 + 960 = 22080
Step 24: 22080 + 960 = 23040
Step 25: 23040 + 960 = 24000
Step 26: 24000 + 960 = 24960
Step 27: 24960 + 960 = 25920
Step 28: 25920 + 960 = 26880
Step 29: 26880 + 960 = 27840
Step 30: 27840 + 960 = 28800
Step 31: 28800 + 960 = 29760
Step 32: 29760 + 960 = 30720
Step 33: 30720 + 960 = 31680
Step 34: 31680 + 960 = 32640

So, 960*34 = 32640
