Alright, let's solve this math problem step by step. First, we have the number 194. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 21. So, we're going to take the number 194 and add it to itself 21 times.
Step 1: 0 + 194 = 194
Step 2: 194 + 194 = 388
Step 3: 388 + 194 = 582
Step 4: 582 + 194 = 776
Step 5: 776 + 194 = 970
Step 6: 970 + 194 = 1164
Step 7: 1164 + 194 = 1358
Step 8: 1358 + 194 = 1552
Step 9: 1552 + 194 = 1746
Step 10: 1746 + 194 = 1940
Step 11: 1940 + 194 = 2134
Step 12: 2134 + 194 = 2328
Step 13: 2328 + 194 = 2522
Step 14: 2522 + 194 = 2716
Step 15: 2716 + 194 = 2910
Step 16: 2910 + 194 = 3104
Step 17: 3104 + 194 = 3298
Step 18: 3298 + 194 = 3492
Step 19: 3492 + 194 = 3686
Step 20: 3686 + 194 = 3880
Step 21: 3880 + 194 = 4074

So, 194*21 = 4074
