Sure thing, let's get straight to it. We start with 612 and we're going to multiply it by 6, which means adding 612 to itself 6 times.
Step 1: 0 + 612 = 612
Step 2: 612 + 612 = 1224
Step 3: 1224 + 612 = 1836
Step 4: 1836 + 612 = 2448
Step 5: 2448 + 612 = 3060
Step 6: 3060 + 612 = 3672

So, 612*6 = 3672
