A scoreboard is simply a form of performance measurement and management thatrecords the ratings from a performance evaluation process.

In standard arithmetic, division is the inverse of multiplication. For example, 10 / 2 = 5 because 5 2 = 10.

If we try to divide a number (let's use 10 again) by zero (10 / 0 = x), it would imply that x 0 = 10. However, any number multiplied by zero is zero, not 10. Because no number 'x' can satisfy this equation, the operation is considered undefined.
