469:00017+73-100

To solve the expression \( 469:00017 + 73 - 100 \), we first need to interpret the notation correctly.

The notation \( 469:00017 \) is a bit ambiguous; if it is intended to represent division, it should be written as \( 469 / 17 \). Assuming that's the case, let's calculate it:

1. Calculate \( 469 / 17 \): \[ 469 \div 17 = 27.5882 \quad (\text{approximately}) \]

2. Now, add 73: \[ 27.5882 + 73 = 100.5882 \]

3. Finally, subtract 100: \[ 100.5882 - 100 = 0.5882 \]

So, the final result is approximately \( 0.5882 \).

If \( 469:00017 \) is meant to be something else, please clarify, and I can recalculate accordingly.
