Let's get this math done. We have 290 and we're going to multiply it by 16. This is the same as taking 290 and adding it to itself 16 times.
Step 1: 0 + 290 = 290
Step 2: 290 + 290 = 580
Step 3: 580 + 290 = 870
Step 4: 870 + 290 = 1160
Step 5: 1160 + 290 = 1450
Step 6: 1450 + 290 = 1740
Step 7: 1740 + 290 = 2030
Step 8: 2030 + 290 = 2320
Step 9: 2320 + 290 = 2610
Step 10: 2610 + 290 = 2900
Step 11: 2900 + 290 = 3190
Step 12: 3190 + 290 = 3480
Step 13: 3480 + 290 = 3770
Step 14: 3770 + 290 = 4060
Step 15: 4060 + 290 = 4350
Step 16: 4350 + 290 = 4640

So, 290*16 = 4640
