OK, let's work through this together. We're starting with 283 and we're going to multiply it by 25, which means we add 283 to itself 25 times.
Step 1: 0 + 283 = 283
Step 2: 283 + 283 = 566
Step 3: 566 + 283 = 849
Step 4: 849 + 283 = 1132
Step 5: 1132 + 283 = 1415
Step 6: 1415 + 283 = 1698
Step 7: 1698 + 283 = 1981
Step 8: 1981 + 283 = 2264
Step 9: 2264 + 283 = 2547
Step 10: 2547 + 283 = 2830
Step 11: 2830 + 283 = 3113
Step 12: 3113 + 283 = 3396
Step 13: 3396 + 283 = 3679
Step 14: 3679 + 283 = 3962
Step 15: 3962 + 283 = 4245
Step 16: 4245 + 283 = 4528
Step 17: 4528 + 283 = 4811
Step 18: 4811 + 283 = 5094
Step 19: 5094 + 283 = 5377
Step 20: 5377 + 283 = 5660
Step 21: 5660 + 283 = 5943
Step 22: 5943 + 283 = 6226
Step 23: 6226 + 283 = 6509
Step 24: 6509 + 283 = 6792
Step 25: 6792 + 283 = 7075

So, 283*25 = 7075
