Alright, let's solve this math problem step by step. First, we have the number 288. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 40. So, we're going to take the number 288 and add it to itself 40 times.
Step 1: 0 + 288 = 288
Step 2: 288 + 288 = 576
Step 3: 576 + 288 = 864
Step 4: 864 + 288 = 1152
Step 5: 1152 + 288 = 1440
Step 6: 1440 + 288 = 1728
Step 7: 1728 + 288 = 2016
Step 8: 2016 + 288 = 2304
Step 9: 2304 + 288 = 2592
Step 10: 2592 + 288 = 2880
Step 11: 2880 + 288 = 3168
Step 12: 3168 + 288 = 3456
Step 13: 3456 + 288 = 3744
Step 14: 3744 + 288 = 4032
Step 15: 4032 + 288 = 4320
Step 16: 4320 + 288 = 4608
Step 17: 4608 + 288 = 4896
Step 18: 4896 + 288 = 5184
Step 19: 5184 + 288 = 5472
Step 20: 5472 + 288 = 5760
Step 21: 5760 + 288 = 6048
Step 22: 6048 + 288 = 6336
Step 23: 6336 + 288 = 6624
Step 24: 6624 + 288 = 6912
Step 25: 6912 + 288 = 7200
Step 26: 7200 + 288 = 7488
Step 27: 7488 + 288 = 7776
Step 28: 7776 + 288 = 8064
Step 29: 8064 + 288 = 8352
Step 30: 8352 + 288 = 8640
Step 31: 8640 + 288 = 8928
Step 32: 8928 + 288 = 9216
Step 33: 9216 + 288 = 9504
Step 34: 9504 + 288 = 9792
Step 35: 9792 + 288 = 10080
Step 36: 10080 + 288 = 10368
Step 37: 10368 + 288 = 10656
Step 38: 10656 + 288 = 10944
Step 39: 10944 + 288 = 11232
Step 40: 11232 + 288 = 11520

So, 288*40 = 11520
