OK, let's work through this together. We're starting with 145 and we're going to multiply it by 11, which means we add 145 to itself 11 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

So, 145*11 = 1595
