OK, let's crack this. We're given 944 and our task is to multiply it by 25. Essentially, we'll be adding 944 to itself 25 times.
Step 1: 0 + 944 = 944
Step 2: 944 + 944 = 1888
Step 3: 1888 + 944 = 2832
Step 4: 2832 + 944 = 3776
Step 5: 3776 + 944 = 4720
Step 6: 4720 + 944 = 5664
Step 7: 5664 + 944 = 6608
Step 8: 6608 + 944 = 7552
Step 9: 7552 + 944 = 8496
Step 10: 8496 + 944 = 9440
Step 11: 9440 + 944 = 10384
Step 12: 10384 + 944 = 11328
Step 13: 11328 + 944 = 12272
Step 14: 12272 + 944 = 13216
Step 15: 13216 + 944 = 14160
Step 16: 14160 + 944 = 15104
Step 17: 15104 + 944 = 16048
Step 18: 16048 + 944 = 16992
Step 19: 16992 + 944 = 17936
Step 20: 17936 + 944 = 18880
Step 21: 18880 + 944 = 19824
Step 22: 19824 + 944 = 20768
Step 23: 20768 + 944 = 21712
Step 24: 21712 + 944 = 22656
Step 25: 22656 + 944 = 23600

So, 944*25 = 23600
