Alright, let's solve this math problem step by step. First, we have the number 16. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 23. So, we're going to take the number 16 and add it to itself 23 times.
Step 1: 0 + 16 = 16
Step 2: 16 + 16 = 32
Step 3: 32 + 16 = 48
Step 4: 48 + 16 = 64
Step 5: 64 + 16 = 80
Step 6: 80 + 16 = 96
Step 7: 96 + 16 = 112
Step 8: 112 + 16 = 128
Step 9: 128 + 16 = 144
Step 10: 144 + 16 = 160
Step 11: 160 + 16 = 176
Step 12: 176 + 16 = 192
Step 13: 192 + 16 = 208
Step 14: 208 + 16 = 224
Step 15: 224 + 16 = 240
Step 16: 240 + 16 = 256
Step 17: 256 + 16 = 272
Step 18: 272 + 16 = 288
Step 19: 288 + 16 = 304
Step 20: 304 + 16 = 320
Step 21: 320 + 16 = 336
Step 22: 336 + 16 = 352
Step 23: 352 + 16 = 368

So, 16*23 = 368
