Because some numbers are irrational and their decimal places are infinite as for example the square root of 2 or the value of pi.
Scientists must sometimes rely on estimates when they cannot obtain exact numbers :)
Scientist often rely the math skill of estimates when they cannot find the exact number.
"Approximately exact" is an oxymoron. An answer can be approximate or it can be exact but it cannot be approximately exact.

I enjoy math sometimes
All other exact sciences are based on math.
Pi is a mathematical constant which represents the ratio of the circumference to the diameter of a circle.Pi is an irrational number, so an exact value cannot be given.Decimal approximation: 3.1415926535897932384626433832795028841971693993751058209749...
No it cannot. Math is an exact science. As it has been said before, A number can either be written as the quotient of two integers or it cannot. You can't have it both ways.

The average verbal is around a 580 and the average math is about a 660. The exact average can be found on the website. The average verbal for the PhD is 643 and for the math is a 695.
When a answer is almost exact in math but not exact you should always use ~ sing, it means similar to
The exact value of 150 would be 3/2. This is taught in high math.
