Step 323: 45080 + 140 = 45220
Step 324: 45220 + 140 = 45360
Step 325: 45360 + 140 = 45500
Step 326: 45500 + 140 = 45640
Step 327: 45640 + 140 = 45780
Step 328: 45780 + 140 = 45920
Step 329: 45920 + 140 = 46060
Step 330: 46060 + 140 = 46200
Step 331: 46200 + 140 = 46340
Step 332: 46340 + 140 = 46480
Step 333: 46480 + 140 = 46620
Step 334: 46620 + 140 = 46760
Step 335: 46760 + 140 = 46900
Step 336: 46900 + 140 = 47040
Step 337: 47040 + 140 = 47180
Step 338: 47180 + 140 = 47320
Step 339: 47320 + 140 = 47460
Step 340: 47460 + 140 = 47600

So, 140*340 = 47600
