Alright, let's solve this math problem step by step. First, we have the number 145. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 43. So, we're going to take the number 145 and add it to itself 43 times.
Step 1: 0 + 145 = 145
Step 2: 145 + 145 = 290
Step 3: 290 + 145 = 435
Step 4: 435 + 145 = 580
Step 5: 580 + 145 = 725
Step 6: 725 + 145 = 870
Step 7: 870 + 145 = 1015
Step 8: 1015 + 145 = 1160
Step 9: 1160 + 145 = 1305
Step 10: 1305 + 145 = 1450
Step 11: 1450 + 145 = 1595
Step 12: 1595 + 145 = 1740
Step 13: 1740 + 145 = 1885
Step 14: 1885 + 145 = 2030
Step 15: 2030 + 145 = 2175
Step 16: 2175 + 145 = 2320
Step 17: 2320 + 145 = 2465
Step 18: 2465 + 145 = 2610
Step 19: 2610 + 145 = 2755
Step 20: 2755 + 145 = 2900
Step 21: 2900 + 145 = 3045
Step 22: 3045 + 145 = 3190
Step 23: 3190 + 145 = 3335
Step 24: 3335 + 145 = 3480
Step 25: 3480 + 145 = 3625
Step 26: 3625 + 145 = 3770
Step 27: 3770 + 145 = 3915
Step 28: 3915 + 145 = 4060
Step 29: 4060 + 145 = 4205
Step 30: 4205 + 145 = 4350
Step 31: 4350 + 145 = 4495
Step 32: 4495 + 145 = 4640
Step 33: 4640 + 145 = 4785
Step 34: 4785 + 145 = 4930
Step 35: 4930 + 145 = 5075
Step 36: 5075 + 145 = 5220
Step 37: 5220 + 145 = 5365
Step 38: 5365 + 145 = 5510
Step 39: 5510 + 145 = 5655
Step 40: 5655 + 145 = 5800
Step 41: 5800 + 145 = 5945
Step 42: 5945 + 145 = 6090
Step 43: 6090 + 145 = 6235

So, 145*43 = 6235
