Sure thing! We've got 240 and we're gonna multiply it by 11. That's the same as adding 240 to itself 11 times.
Step 1: 0 + 240 = 240
Step 2: 240 + 240 = 480
Step 3: 480 + 240 = 720
Step 4: 720 + 240 = 960
Step 5: 960 + 240 = 1200
Step 6: 1200 + 240 = 1440
Step 7: 1440 + 240 = 1680
Step 8: 1680 + 240 = 1920
Step 9: 1920 + 240 = 2160
Step 10: 2160 + 240 = 2400
Step 11: 2400 + 240 = 2640

So, 240*11 = 2640
