Alright, let's solve this math problem step by step. First, we have the number 303. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 50. So, we're going to take the number 303 and add it to itself 50 times.
Step 1: 0 + 303 = 303
Step 2: 303 + 303 = 606
Step 3: 606 + 303 = 909
Step 4: 909 + 303 = 1212
Step 5: 1212 + 303 = 1515
Step 6: 1515 + 303 = 1818
Step 7: 1818 + 303 = 2121
Step 8: 2121 + 303 = 2424
Step 9: 2424 + 303 = 2727
Step 10: 2727 + 303 = 3030
Step 11: 3030 + 303 = 3333
Step 12: 3333 + 303 = 3636
Step 13: 3636 + 303 = 3939
Step 14: 3939 + 303 = 4242
Step 15: 4242 + 303 = 4545
Step 16: 4545 + 303 = 4848
Step 17: 4848 + 303 = 5151
Step 18: 5151 + 303 = 5454
Step 19: 5454 + 303 = 5757
Step 20: 5757 + 303 = 6060
Step 21: 6060 + 303 = 6363
Step 22: 6363 + 303 = 6666
Step 23: 6666 + 303 = 6969
Step 24: 6969 + 303 = 7272
Step 25: 7272 + 303 = 7575
Step 26: 7575 + 303 = 7878
Step 27: 7878 + 303 = 8181
Step 28: 8181 + 303 = 8484
Step 29: 8484 + 303 = 8787
Step 30: 8787 + 303 = 9090
Step 31: 9090 + 303 = 9393
Step 32: 9393 + 303 = 9696
Step 33: 9696 + 303 = 9999
Step 34: 9999 + 303 = 10302
Step 35: 10302 + 303 = 10605
Step 36: 10605 + 303 = 10908
Step 37: 10908 + 303 = 11211
Step 38: 11211 + 303 = 11514
Step 39: 11514 + 303 = 11817
Step 40: 11817 + 303 = 12120
Step 41: 12120 + 303 = 12423
Step 42: 12423 + 303 = 12726
Step 43: 12726 + 303 = 13029
Step 44: 13029 + 303 = 13332
Step 45: 13332 + 303 = 13635
Step 46: 13635 + 303 = 13938
Step 47: 13938 + 303 = 14241
Step 48: 14241 + 303 = 14544
Step 49: 14544 + 303 = 14847
Step 50: 14847 + 303 = 15150

So, 303*50 = 15150
