Sure thing, let's get straight to it. We start with 320 and we're going to multiply it by 36, which means adding 320 to itself 36 times.
Step 1: 0 + 320 = 320
Step 2: 320 + 320 = 640
Step 3: 640 + 320 = 960
Step 4: 960 + 320 = 1280
Step 5: 1280 + 320 = 1600
Step 6: 1600 + 320 = 1920
Step 7: 1920 + 320 = 2240
Step 8: 2240 + 320 = 2560
Step 9: 2560 + 320 = 2880
Step 10: 2880 + 320 = 3200
Step 11: 3200 + 320 = 3520
Step 12: 3520 + 320 = 3840
Step 13: 3840 + 320 = 4160
Step 14: 4160 + 320 = 4480
Step 15: 4480 + 320 = 4800
Step 16: 4800 + 320 = 5120
Step 17: 5120 + 320 = 5440
Step 18: 5440 + 320 = 5760
Step 19: 5760 + 320 = 6080
Step 20: 6080 + 320 = 6400
Step 21: 6400 + 320 = 6720
Step 22: 6720 + 320 = 7040
Step 23: 7040 + 320 = 7360
Step 24: 7360 + 320 = 7680
Step 25: 7680 + 320 = 8000
Step 26: 8000 + 320 = 8320
Step 27: 8320 + 320 = 8640
Step 28: 8640 + 320 = 8960
Step 29: 8960 + 320 = 9280
Step 30: 9280 + 320 = 9600
Step 31: 9600 + 320 = 9920
Step 32: 9920 + 320 = 10240
Step 33: 10240 + 320 = 10560
Step 34: 10560 + 320 = 10880
Step 35: 10880 + 320 = 11200
Step 36: 11200 + 320 = 11520

So, 320*36 = 11520
