OK, let's work through this together. We're starting with 236 and we're going to multiply it by 7, which means we add 236 to itself 7 times.
Step 1: 0 + 236 = 236
Step 2: 236 + 236 = 472
Step 3: 472 + 236 = 708
Step 4: 708 + 236 = 944
Step 5: 944 + 236 = 1180
Step 6: 1180 + 236 = 1416
Step 7: 1416 + 236 = 1652

So, 236*7 = 1652
