Alright, let's solve this math problem step by step. First, we have the number 320. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 27. So, we're going to take the number 320 and add it to itself 27 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

So, 320*27 = 8640
