What happens here

To calculate a precise 10% tip, start with the total bill amount (e.g., $17.76). Move the decimal point one place to the left, which for $17.76 would be $1.776. The presenter then suggests rounding this number. If the third decimal place is 5 or greater, round the second decimal place up. In the example, $1.776 is rounded to $1.78, which represents the 10% tip.

Goal: Calculate an accurate 10% tip from a given bill amount.
