Let's get this math done. We have 216 and we're going to multiply it by 32. This is the same as taking 216 and adding it to itself 32 times.
Step 1: 0 + 216 = 216
Step 2: 216 + 216 = 432
Step 3: 432 + 216 = 648
Step 4: 648 + 216 = 864
Step 5: 864 + 216 = 1080
Step 6: 1080 + 216 = 1296
Step 7: 1296 + 216 = 1512
Step 8: 1512 + 216 = 1728
Step 9: 1728 + 216 = 1944
Step 10: 1944 + 216 = 2160
Step 11: 2160 + 216 = 2376
Step 12: 2376 + 216 = 2592
Step 13: 2592 + 216 = 2808
Step 14: 2808 + 216 = 3024
Step 15: 3024 + 216 = 3240
Step 16: 3240 + 216 = 3456
Step 17: 3456 + 216 = 3672
Step 18: 3672 + 216 = 3888
Step 19: 3888 + 216 = 4104
Step 20: 4104 + 216 = 4320
Step 21: 4320 + 216 = 4536
Step 22: 4536 + 216 = 4752
Step 23: 4752 + 216 = 4968
Step 24: 4968 + 216 = 5184
Step 25: 5184 + 216 = 5400
Step 26: 5400 + 216 = 5616
Step 27: 5616 + 216 = 5832
Step 28: 5832 + 216 = 6048
Step 29: 6048 + 216 = 6264
Step 30: 6264 + 216 = 6480
Step 31: 6480 + 216 = 6696
Step 32: 6696 + 216 = 6912

So, 216*32 = 6912
