Sure thing, let's get straight to it. We start with 150 and we're going to multiply it by 10, which means adding 150 to itself 10 times.
Step 1: 0 + 150 = 150
Step 2: 150 + 150 = 300
Step 3: 300 + 150 = 450
Step 4: 450 + 150 = 600
Step 5: 600 + 150 = 750
Step 6: 750 + 150 = 900
Step 7: 900 + 150 = 1050
Step 8: 1050 + 150 = 1200
Step 9: 1200 + 150 = 1350
Step 10: 1350 + 150 = 1500

So, 150*10 = 1500
